On/Off & Shut Off Valves
Like the name suggests, on/off valves are designed to shutoff and to open fully with no ability to regulate effectively through the range of travel.
Although the functioning of an on/off valve is simpler than a control valve, providing for highly reliable and repeatable tight shutoff can be equally challenging. Shutoff valves often provide a safety function as they are called to stop flow quickly and positively as in a gas service shutoff valve or a heat activated shutoff valve. High actuation force, resilient seated trim, long life hardened seating materials and exacting seal geometry are a few of the many engineering solutions deployed by CIRCOR Energy to ensure high integrity, repeatable tight shutoff performance.
On/ off valves from CIRCOR Energy include manual stop valves with bellows seal, a variety of gas turbine on/off valves, general purpose electrically actuated shutoff valves and butterfly valves for compressor air extraction and. Our solenoid operated shutoff valves from demonstrate reliable performance even with stroking times in fractions of a second. All CIRCOR Energy on/off valves are designed to provide reliable shutoff over a wide range of service conditions.
