Installation and Removal of CPV’s New Handles

The process of installing and removing our new ergonomic valve handles for the full-size range of O-SEAL® and G-Series® product lines is so simple it can be done in under a minute! The ease of installation can be seen below in the step by step tutorial.

This specific bulletin shows the installation of a 4-prong valve handle; however, the same steps apply to our 2-prong valve handles. The only difference is and additional step due to an extra washer in the replacement kit, also shown below. During installation and removal of a 2-prong handle, the extra step would occur after step 2 for both.

Installation and Removal of CPV's New Handles


For extra guidance, we have listed all the removal steps below and made an in-depth YouTube tutorial showing just how simple the installation and removal of our new valve handles really are!

Removal Steps:

Step 1: Using the Handle Installation Tool, pick out one end of the Snap Ring and lift it out of the groove. Be sure to place your hand over the ring to keep it from flying away and becoming lost.

Step 2: Remove the Cap covering the Hex Nut.

Step 3: Remove the Hex Nut with a Socket Wrench. The handle should then come right off the valve.

5 Things You Should Know About Monel®

In the engineering sphere, you’re used to working with various forms of metal,
especially machined valves and fittings.

These types include Monel®, which is the name given to nickel-based alloys
that contain mostly nickel and copper, along with trace amount of carbon, iron,
manganese, and silicon.

Today, we’re diving into this material and sharing five facts you might not
know about it. Ready to learn more? Let’s get started.

1. Monel® is More Versatile Than You Thought

With its trademark high-corrosion resistance and tensile strength, Monel® can
fit a variety of applications and use cases. It’s also easy to braze, weld and

As such, manufacturers can mold it into the following forms, among others:

  • Castings
  •  Forgings
  •  Wires
  •  Sheets
  •  Rods
  •  Tubes
  •  Plates
  •  Nuts
  •  Bolts
  •  Rivets
  •  Nails
  •  Screws
  •  Tube fittings
  •  Fasteners
  •  Valves

While Monel®400 is one of the most common types, you can also find Monel®
401, 405, 450, K-500, and related models. All will display the trademark of
Special Metals Corporation.

2. It’s Saltwater-Friendly

Monel® is resistant to deterioration, rust, and corrosion. This makes it ideal for
equipment parts that are present in chemical and marine environments. Some
main market applications in this area include:

  •  Piping systems
  • Pump shafts
  •  Trolling wire
  • Seawater valves & environments
  • Strainer baskets
  • Chemical and hydrocarbon processing equipment

Due to its high corrosion resistance to acids, oxygen and alkalis, you'll find
Monel® in chemical plant equipment. It also retains its strength at very high
temperatures, leading to widespread use in the aerospace industry.

3. It Helps Make Music

Monel® first entered the music industry in 1962, when a flat ribbon of Monel®
400 was used in electric bass strings.

Now, you can also find it in the valve pistons or rotors of some of the finest-
quality instruments in the world, including tubas, trumpets and French horns.

4. The Patent Dates Back to 1905

In 1905, metallurgist Robert Crooks Stanley created the metal. He patented it
through the company he worked for, the International Nickel Company

He named it Monel® after the company’s then-director, a role that he would
assume years later.

5. It Was Once a Household Name

That steel sink in your kitchen would have been a Monel® one a few decades

One of the first uses of Monel® was as a roofing material for Pennsylvania
Station in New York City in 1908. Then, from the 1920s to the 1940s, it
became one of the most common household materials on the market, used to
create sinks, appliances, and even countertops.

When more affordable stainless steel entered the industry in the 1950s,
interior design attention often diverted away from Monel®. Today, savvy
shoppers can still find vintage originals for their retro kitchens!

How Will You Use Monel®?

Monel® is a powerful player in the engineering space, heralded for its strength
and durability. Whether you’re looking for a heat exchanger, wind instrument,
piping system water tank, or any other resource, it’s a go-to resource and
industry mainstay.

Looking for quality machined valves and fittings to help tie your systems
together? That’s where we come in.

Everything You Need to Know: 316L Stainless Steel

Did you know that low carbon steel alloys have a carbon content from 0.01% up to 0.3%? these alloys are used to make different types of objects and metal components such as fasteners, bolts, medical tools, shafts, spindles, and more.

One of the most popular types of low carbon steel is the 316l stainless steel alloy. This metal contains up to 0.03% carbon and it can be very easy to work with. You should not confuse the 316l alloy with the plain 316 stainless steel because there are important differences between them. Keep reading to find out more!

316l Stainless Steel 101 – Everything You Need To Know

One of the main differences between 316l stainless steel and 316 stainless steel is that the former contains up to 0.03% carbon and the later contains up to 0.08% carbon. These differences give them various properties. Let’s learn more about 316l stainless steel alloy.

1. 316l Is More Suitable for High-Corrosion Use

The 316l stainless steel alloy is used in various applications because it’s great at avoiding weld corrosion. It can also withstand high temperatures and it has a high melting point at around 2,500 degrees Fahrenheit or about 1,370 degrees Celsius. Apart from carbon, this alloy also contains up to 2% manganese and up to 0.75% silicon.

2. 316l Is Used In Multiple Applications and Industries

Unlike other types of steels such as 304 and 306, the 316l stainless steel alloy can be found in various applications where high resistance to corrosion is necessary. For example, experts use it in the chemical and pharmaceutical industry for making surgical tools and medical implants.

This alloy can also be used for making textile tubing as well as equipment for the petroleum refining industry. 316l steel has high formability which means that it can be bent and cut in various ways without damaging it. As a result, it’s also used for ductworks, for making ozone generators or sewage water filters.

3. 316l Comes In Various Shapes

Thanks to the fact that this alloy is easy to work with and can’t be easily damaged, companies bend it in various shapes and forms. For example, 316l stainless steel comes as ribbons, wires, sheets, strips, and other shapes. Each industry manipulates this metal with great success to create various finished products.

4. Understanding the Differences Between 316l and 316 Stainless Steel

Although both of these steels are considered to be low carbon steel alloys, they are quite different. For example, the “L” stands for “low” in 316l stainless steel and signifies that this alloy has a very low carbon content. The 316l variant is also more resistant to weld decay in comparison with 316 and it can withstand higher temperatures. That’s why 316l is used often in marine and construction projects.

Take Your Steel Knowledge to The Next Level

The 316l stainless steel alloy is a staple in today’s metallurgy industry and it can be tailored to accommodate the needs of your business. Make sure that you contact us today to learn more about steel fabrication and how our supplies of 316l stainless steel can benefit your company!
