Special function valves for flow control, pneumatic logic, speed improvement, and safety applications.
——————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————
Special function valves perform specific logic, speed, or control tasks that standard directional control valves cannot handle. Our range includes:
● Shuttle Valves (OR Logic) – Select between two pressure sources, ideal for backup air supply
● Quick Exhaust Valves – Dramatically increase cylinder retraction speed by providing a direct exhaust path
● Flow Control Valves – For precise cylinder speed regulation (see our Tubings & Fittings section for throttle valves)

Note on Flow Control Valves:
● Need a compact, inline throttle valve for direct cylinder mounting?
Visit our [Throttle Valves in Tubings & Fittings →] for push-in type speed controllers (SC, SU series).
● Need a panel-mount, high-flow, or valve-body type flow control valve?
Contact us for RE, ASC series options.

Additional Special Function Valves (Coming Soon):
● Dual Pressure Valves (AND Logic) – For two-hand safety control
● Lock-up Valves (Air Lock) – For position holding during air failure

Q1: What is a shuttle valve used for?
A1: A shuttle valve (OR logic) selects between two pressure sources. Common uses include backup air supply or alternative control stations.
Q2: What does a quick exhaust valve do?
A2: A quick exhaust valve increases cylinder return speed by providing a larger, more direct exhaust path to atmosphere, bypassing the control valve.
Q3: Do you offer dual pressure valves or lock-up valves?
A3: These are in our product roadmap. Please contact us with your requirements, and we'll check availability or lead time.
