CHECK VALVE（HK3）■Features
A check valve allows fluid flow in one direction only while maintaining the specified
cracking pressure, and completely stops the flow in the reverse direction.
These valves are classified into two types according to the body shape, namely the
inline type and the right-angle type.
● If subplate SHK**-**T1(A) is necessary, please order one separately.
● For the gasket-connection type check valves, finish the mounting faces to thesame quality as the valve faces (3.2 µmRz).

CHECK VALVE（HK3ｰEFT005ｰ*）■FeaturesThis type of check valve consists of a check valve that prevents reverse rotation of thepump and a pump out side flange assembled in one unit, aiming at a reduction inpiping work hours and saving of installation space.
Please read the Operating Manual
carefully to ensure correct usage.

Cautions on use● Finish the mounting faces to the same quality as the valve faces (3.2 µmRz).
