Choose by operator type
First choose whether the valve is hand operated, mechanically actuated, foot operated or used for flow/direction control. Then match port size and circuit function.
Speed and exhaust control
Use one-way throttle valves to tune cylinder speed and quick exhaust valves when the circuit needs faster exhaust near the actuator.
RFQ confirmation
Send function, port size, model code if available, working pressure, mounting position, quantity and photos when replacing an existing part.

Frequently Asked Questions
- FAQ What is the difference between a throttle valve and a quick exhaust valve?
A throttle valve controls air flow to adjust motion speed. A quick exhaust valve vents air near the actuator to reduce exhaust path resistance. - FAQ Can Kailing quote manual valves without a model code?
Yes, but buyers should send the valve function, operator type, number of ports/positions, port size, pressure and photos or drawings.
Need a quotation?
Send the model, medium, pressure, port size, body material and quantity for review.
