Stainless Steel/ Carbon Steel Life Wafer Type Check Valve 150lb/ Pn16

stainless steel/ carbon steel lug type wafer check valve This valve consists of two plates hinged on a single pin. The load is carried by two plates supported at the center by a single beam the the cylindrical valve body. The curved portion of the plates are supported by a flat shoulder in the valve body. The torsion spring actuates the plates for positive closure before the reverse flow can occure in most applications. The stop pin serves as a positive stop to limit the plates from traveling more than 85 degrees. Design Standard: API 594, API 6D, JB/T 8937. Face to face: API594, API 6D, DIN 3202, JB/T 8937. Connection: Lugged type Connection standard: ANSI B 16.5, DIN 2543 C2548, API 605, ASME B 16.47.
