Features and benefits
Check valves are installed to allow flow in one direction only and they protect systems that can be affected by reverse flow, such as a system shutdown. They are operated entirely by reaction to the flow and therefore do not require external actuation. Care and attention should be paid to check valve installation orientation.
- Velan small forged steel check valves comply to API 602 and ASME B16.34 standards.
- A compact but extremely sturdy design for high pressure-temperature service.
- Quick and easy repair in the line.
- Available types: Piston, ball, swing check
