Frequently Asked Questions
How do FloMaster® Actuated (Shutoff) Valves work?
FloMaster® Actuated (Shutoff) Valves are pneumatic valve actuators that use compressed air to automate the operation of valves in various industrial applications. Utilizing proven positive shutoff technology, these systems control the flow of gas effectively. They offer more accurate control of gas flow, reduce the risk of leaks, extend valve life, simplify operation and enhance safety.
Do they provide a leak-proof installation?
CPV recommends using FloMaster® valves with the O-SEAL® body, which is manufactured to exacting standards, to ensure a leak-free installation.
Do you have an option for space saving?
Yes, CPV recommends using FloMaster® valves with the G-Series® body that has a compact, yet robust design.
What is an actuated shutoff valve and how does it operate?
An actuated shutoff valve combines a quarter-turn or linear valve body with an automatic actuator system (pneumatic, electric, or hydraulic) to provide remote on-off control capability without manual intervention. The actuator receives control signals from process control systems, safety systems, or manual switches to rapidly open or close the valve. By this action, the actuated shutoff valve enables automated process control, initiates emergency shutdown, or provides safety isolation functions.
CPV Manufacturing’s FloMaster® line of pneumatically operated actuated valves exemplifies this technology, providing fail-safe shutoff capability for high-pressure applications up to 6,000 PSI leveraging its proven O-SEAL® technology for leak-proof performance in automated systems.
What types of actuators are used for shutoff valves?
Among the type of actuators used for shutoff valves there are a few primary categories. Pneumatic actuators utilize compressed air for rapid operation with fail-safe capability, electric actuators offer precise positioning and digital integration and hydraulic actuators provide exceptional force for large valves or high-pressure applications. Each type can be configured with fail-safe features to automatically move to a predetermined safe position upon power or signal loss.
CPV Manufacturing’s comprehensive understanding of actuator technologies enables them to recommend optimal configurations for specific application requirements and safety specifications.
When should I use an actuated shutoff valve instead of a manual valve?
Engineers and facility operators choose actuated shutoff valves when applications require remote operation capability, rapid emergency response times that manual operation cannot achieve, or when valves are located in hazardous environments where personnel access is unsafe or impractical.
Industries requiring automated process control, integration with safety instrumented systems, or consistent performance regardless of operator availability also benefit from actuated valves rather than manual alternatives. CPV Manufacturing’s FloMaster® actuated valve line serves customers in industrial gas filling, petrochemical processing and other critical applications where automated, fail-safe operation is essential for safety and operational efficiency.
How do fail-safe actuated shutoff valves work?
Fail-safe actuated shutoff valves incorporate spring-return or stored energy mechanisms that automatically drive the valve to a predetermined safe position when actuating power is lost, control signals fail, or emergency conditions are detected. The fail-safe action can be configured as fail-closed for containment applications or fail-open for cooling or relief applications. CPV Manufacturing’s experience in designing valves for critical safety applications ensures their actuated shutoff valves provide reliable fail-safe operation when safety depends on it.
What industries and applications commonly use actuated shutoff valves?
Actuated shutoff valves serve critical roles in industrial gas automated cylinder filling plants, petroleum refining, chemical processing, power generation, marine applications, and industrial manufacturing where rapid, reliable shutoff capability is required for safety systems and automated process control. The offshore oil and gas industry particularly relies on these valves for subsea installations and platform safety systems where manual operation is impossible. CPV Manufacturing’s extensive experience serving critical industries, including their long-standing relationship with the US Navy and involvement in space programs, positions them to provide actuated shutoff valve solutions that meet the most demanding safety and performance requirements.
What performance standards and tests are required for actuated shutoff valves?
Performance standards and tests required for actuated shutoff valves will include:
- Closure time specifications.
- Leakage rate testing per API 598 or equivalent.
- Endurance testing for specified cycle counts.
- Environmental qualification for:
- Temperature.
- Vibration.
- Corrosive conditions.
Safety-critical applications require additional testing including partial stroke testing, proof testing at specified intervals, and Safety Integrity Level (SIL) verification. CPV Manufacturing’s commitment to quality and testing, demonstrated through their supply to demanding applications including naval vessels and space programs, ensures their actuated shutoff valves meet or exceed all applicable performance standards and testing requirements.
What should be considered when selecting an actuator for an actuated shutoff valve?
Actuator selection must account for proper sizing to match valve load capacity, required torque or thrust under maximum differential pressure conditions, response speed requirements, available power sources and environmental conditions including temperature extremes and corrosive atmospheres.
Additional considerations include control signal compatibility, position feedback requirements and fail-safe requirements for safety applications. CPV Manufacturing’s engineering expertise in matching actuators to valve requirements ensures optimal performance and reliability for specific application demands.
How do I prevent water hammer or pressure surges when an actuated shutoff valve closes suddenly?
Water hammer prevention strategies include controlling valve closing speed through actuator programming, installing pressure relief or surge suppression devices downstream and using soft-seat designs that provide gradual shutoff rather than abrupt closure. Additional protection methods include installing air chambers, surge tanks, or pressure relief valves to absorb pressure spikes. CPV Manufacturing’s experience with high-pressure systems and their understanding of flow dynamics enable them to recommend actuated shutoff valve configurations that minimize water hammer while meeting safety and operational requirements.
Can actuated shutoff valves be integrated into automated control systems?
Modern actuated shutoff valves readily integrate with PLCs, DCS, SCADA systems and Building Management Systems through standardized communication protocols including 4-20 mA analog signals, digital protocols like HART or Foundation Fieldbus and discrete input/output signals.
Advanced integration features include valve position feedback, diagnostic information transmission and predictive maintenance data collection. CPV Manufacturing’s understanding of modern control system requirements enables them to provide actuated shutoff valve solutions with the communication and integration capabilities needed for sophisticated automation and safety systems.
