Pilot-Operated Check Valves
This is a check valve with a check release（reverse flow）mechanism that is operated by a signal pressure.
Shuttle Valves
A shuttle valve has two supply ports and one discharge port.When air pressure is admitted through one supply port,the other supply port is closed and the air pressure is transferred to the discharge port.
Quick-Release Valves
The quick-release valve is installed between directional control valves and actuators such as cylinders,and is operated by the discharge action of the directional control valve.It is used to further increase the discharge volume of the actuator for greater operating speed（up to 1.4 times）.
Safety Block Valves
This is a safety line component that installed between three-position directional control valves and cylinders. It is used to ensure that the cylinder is held in the mid-position when stopped at the middle of its stroke. It protects equipments against accidents that may result from the cylinder unexpectedly moving from its middle stopping position.
Lockup Valves
This valve responds to abnormal drops in the supply air pressure in the pneumatic line,ensuring that the set pressure for the driven unit is maintained until the supply pressure returns to normal. It also locks the actuator to prevent unexpected movements if the supply pressure varies.
Slow-Start Valves
SSV2：Standard type（Port size：Rc3/8 , Rc1/2）
Pressure Detection Valves
This valve detects signal pressure（air pressure）and controls other valves to which it is attached；when mounted on a shutoff valve, for example,it operates the shutoff valve if it detects a signal pressure drop.
Speed Controllers
The speed controller is installed on actuators such as cylinders and air motors,and controls the operating speed of the actuator by adjusting the flow through the actuator.
