Check Valve

Hyper-connection & Hyper-intelligence Control System Leader

CHECK VALVE

• Quick operations (Quick closing) to reveres flow.
• Little damages od disk stopper for frequent operations.
• High perdormance with the low differrntial pressure without any chattering.

SWING CHECK VALVE

• Opened automatically at the forward flow and closed at the reverse flow. The disk IS held by an arm which rotates on a pin contained in the seat upon exertion of fluid pressure on the reversal pressure and the weight of the disk close the disk against the seat, stopping back flow.
• Can be installed horizontal pipe line, and can also be installed the vertical position (upward flow only through valve).
• This design keeps minimize the stress, turbulence and resistance to flow.
• Body penetration is sealed with blind flange and seal ring (Inner shaft type is available without body penetration).
• This type of valve has an advantage light weight and easy maintenance.
• This type valve is best suited for moderate velocity applications
