SRQ - Quick Exhaust
Fast-acting exhaust valve enhancing actuator speed with direct discharge, ensuring rapid operation.
Enhances actuator speed by directly exhausting air, reducing response time for faster operation.
Versatile configurations allow selection of size, material, and temperature rating to suit various applications.
Reliable performance ensures smooth operation without hunting, maximising system efficiency.
The SRQ Quick Exhaust Valve is designed to enhance actuator response time by expelling exhaust air directly into the atmosphere. Used in conjunction with solenoid valves or positioners, this valve increases actuator speed without hunting, ensuring reliable and precise operation. Available in multiple sizes, materials, and temperature ratings, it supports a wide range of pneumatic applications. Its robust construction and optimised design minimise pressure loss while maximising flow efficiency. The SRQ valve is ideal for applications requiring rapid opening or closing of actuated systems in process industries, offering improved performance and operational reliability.
