Valve Spacers

CPV Valve Spacers are the exact face-to-face dimension of CPV O-SEAL® valves. They can be used to protect valves during installation, and can be reused again and again for maintenance operations.

CPV O-SEAL® valves provide years of reliable service. However, the heat of welding or brazing during installation can compromise the cleanliness and/or integrity of the O-SEAL® valve. Using CPV’s hollow core valve spacers enables users to avoid that risk. These spacers replicate the exact face-to-face dimension of the O-SEAL® valve being installed. After welding or brazing has taken place, the entire system can be flushed. The spacer is then slipped out and the valve slipped in. Users are thus assured of both a perfect fit and a leakproof connection for years to come. Moreover, once the O-SEAL® Valve is in service, the valve spacer can be saved and re-used over and over again. For example, if flushing the system could cause problems or contaminate the O-SEAL® Valves, users simply slip the valves out and slip the spacers in.

To order, enter the letter “F” in front of the part number for the CPV O-SEAL® valve you are installing. Be sure to specify the complete

part number for each spacer you wish to order, including the size code or “dash” number. For example:

image

image

image

image

F-380-3 (spacer for Globe Valve No. 380-3, size 1/2”) F-381-4 (spacer for Angle Valve No. 381-4, size 3/4”) F-123A-5 (spacer for Check Valve No. 123A-5, size 1”)


Valve Flush Plugs

If one section of a piping system needs to be altered, cleaned or flushed, CPV O-SEAL® Flush Plugs can be used to protect the rest of a system from contamination. Simply remove the valve cartridge and insert the appropriate Flush Plugs into the O-SEAL® valve bodies at either end of the affected area and the rest of the system will be totally cut off from the cleaning or flushing process.

There are three types of flush plugs available: Under-Seat, Over-Seat, and Flow-thru.

image

As can be seen in the schematic drawings, the Over-Seat and Under-Seat have threaded connections in the top of the plug for

trouble-free connection to the flushing pump. The Flow-Thru Plugs are intended for insertion in valves located in the middle of the section being flushed or cleaned. Once installed, these plugs allow the flush to flow through without contaminating the O-SEAL® valve cartridges. When these valve bodies are equipped with O-SEAL® Flush Plugs, future system expansion or section flushing will be much easier.


Soft Goods Kits

image

In the event that the sealing elements used in an O-SEAL® system valve ever need replacement, a soft goods kit can be obtained containing all four of the items required. To order a soft goods kit, determine the proper material grouping shown across the top of the chart below. Read down the column and select the Kit Number on the horizon line matching the valve size or Dash Number.

For example:

A 1/2 in. 380-3 Globe valve requires a soft goods kit. The valve is used in com- pressed air service, and the compressor is lubricated with a petroleum-based oil. The materials listed in the first column under Material Grouping B are satisfactory for this service.

Continue down this column to the line for Dash No. -3 (1/2 in. pipe size) to

determine that the Kit Number is 003803.


image

*Maximum temperature rating of standard valve assembly is limited by Nylon disc at 275°F (135°C).

**Note: If a Vacuum Service valve is ordered (-VC), simply add “-VC” to the end of the Kit Part Number to ensure that the additional softgoods will be supplied for that -VC valve.

Example: 003813-VC


image


Stem Seal Tools

image

Every new CPV O-SEAL® valve provides leakproof assurance to up 6000 PSI

(413 bar). Properly maintained they should provide long, reliable service. The stem seals are made of Viton®, Polyurethane, Ethylene Propylene, etc. and should be inspected at appropriate intervals depending on system conditions and frequency of use. To maintain CPV’s leakproof standard after stem seal replacement, the “U” cup installation tool developed by CPV should be used. This tool is easy to use and enables users to replace a stem seal in less than a minute. By compressing the outer sealing lip and expanding the inner lip, the kit makes it easy to slip the “U” cup stem seal over the valve stem. Once the stem seal is properly installed on the valve stem, it can be easily inserted into the bonnet gland and secured without damaging the critical edges of the seal. A CPV Replacement Soft Goods Kit can also be ordered in the pipe size and soft goods material specified for the user’s application. This kit contains one of each: stem seal, body O-ring, back-up ring, and seat O-ring.


image


The CPV “U” Cup Installation Tool can be used on O-SEAL® Shutoff, Needle, or Stop-Check valve cartridges.


image

The relevant part numbers are as follows:

image

Shutoff: 365, 370, 371, 380, 381, and 382

image

Needle: 465, 470, 471, 480, 481, and 482

image

Stop-Check: 565, 570, 571, 580, 581, and 582


How to Install “U” Cup Stem Seals in CPV O-SEAL® System Valves


image image image image

1. Insert items A and C onto item B. 2. With the sealing lips facing away

from the tool, slide the “U” cup over

the taper on item A.

  1. Continue to press the “U” cup over item A until the cup is stopped by the shoulder of item B. At the same time, pull up on item C until it covers the “U” cup.

  2. Remove item A.


    image image image image

  3. Invert items B and C with the “U” cup. Slip the tool assembly over the valve stem and into the bonnet gland.

  4. Hold down item C while removing item B.

  5. Insert item D. 8. Press down on item D to seat the “U” cup in the gland. Remove tool assembly.

Silent Check Valve Engineering Data


image

CPV Silent Check Valves employ a specially-engineered stainless steel helical spring which closes the valve automatically and silently at the instant of zero flow velocity - not after reverse flow has begun, like standard industry swing-check valves. No reverse flow means no

dangerous pressure surge, therefore no destructive water hammer is experienced.


Actual oscillograph readings illustrate the difference in the potential of pressure surge between a standard swing check

valve and a CPV Silent Check Valve.


Here, the first graph shows dangerous pressure surges caused by normal closure of a 3” swing check valve in an 850 PSI system. Note that the valve closure caused a pressure jump from 850 PSI up to 1788 PSI - more than double the operating pressure.


The second graph shows a 3” CPV Silent Check Valve reading with minimal pressure fluctuation. There was no dangerous pressure surge. No chance for water hammer.


CPV Silent Check Valves overcome the inadequacies of all other check valve designs and methods. Operation is automatic and foolproof. Reverse flow is stopped before it can start. Water hammer and its accompanying ill-effects are eliminated. A safe, silent piping system is assured.

Silent Check Valve Engineering Data


All CPV Silent Check Valves feature a streamlined design and full flow through the valve body, thus assuring minimum

Head loss and gpm curves for Silent Check Valve Part Numbers:

image

image

image

10D, 11D, 12D, 13D, 20D, and 21D (See page 74 for ordering information) 110D, 111D, 113D, 114D, and 115D (See page 75 for ordering information) 14D, 15D, 16D, 17D, 125D, and 126D (See page 76 for ordering information)


These curves indicate the nominal amount of head loss for the flow of water through CPV Silent Check Valves of various sizes. Valve size is indicated at the top of each curve.

For example, in a 4” pipe line, the anticipated flow is 320 gpm. As the blue dotted line indicates, the head loss for a 4”

CPV Silent Check Valve at 320 gpm is approximately 2.2 PSI or 5 ft. of water.

Also indicated on the chart is flow velocity in feet per second, and it should be noted that in the example, the dotted line intersects the 4” valve size curve at the 8 fps curve. Since head loss varies with the square of the flow velocity, good engineering practice dictates that a velocity of 10 ft. per sec. should not be exceeded.

*Discharge capacities are computed for set pressure plus accumulation

(or overpressure) shown in tables with air and

water at ambient conditions.

Notes:

  1. Formulas used to calculate capacities are derived from API

    Recommended Practice 520 and ASTM F1508.

  2. Relief Valve Standards: Set Pressure Tolerance: ±2%

Reseat (Blowdown) Pressure Tolerance: -7%
