Check Valves
The check valve permits only one-way air flow and prevents reverse flow.Konan's check valves are designed for low cracking pressure and very low resistance to air.
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.
