Dual Function | Reliable Backflow Prevention | Positive Shut-Off
Stop Check Valve
Stop check valves, also known as stop plate check valves, combine the features of a check valve with the added functionality of a shut-off valve. These versatile valves automatically prevent reverse flow under normal operating conditions and, when required, can be manually or actuated to stop forward flow as well. This dual functionality provides operators with greater control, enhanced safety, and reduced need for additional valve installations, making them a cost-effective and efficient solution in critical flow systems.
Applications
- Backflow Prevention in pumping and process systems
- Emergency Shut-Off in critical service lines
- Flow Regulation & Isolation in high-pressure and high-temperature systems
- Protection of Pumps, Boilers & Compressors against reverse flow damage
- Critical Process Systems where automatic and manual control are both required
Industries Served
- Oil & Gas – Pipeline isolation and safety in upstream, midstream, and downstream operations
- Power Generation – Boiler feedwater, steam, and condensate systems
- Petrochemical & Chemical – High-pressure and corrosive process lines
- Water & Wastewater – Pumping stations, treatment plants, and critical distribution networks
- Marine & Offshore – Dual-function flow control for compact systems
- Industrial Utilities – Steam, air, and gas distribution requiring safety shut-off and backflow protection
Key Advantages
- Combines check valve and stop valve functions in one unit
- Provides automatic backflow prevention and positive shut-off when needed
- Reduces need for multiple valve installations, saving space and cost
- Rugged construction suitable for high-pressure, high-temperature service
- Available in manual, electric, or pneumatic actuation options
