Product catalog summary
Overview: The V701 Series Wafer Type Swing Check Valves are designed for a range of applications including fresh, sea, waste water, steam, acids, and alkaline liquids. They are available in sizes from DN40 to DN600 and are compliant with EN 1074-3 and EN 12266-1 standards.
Specifications: These valves feature a very low weight and ultra-short face-to-face dimensions. They include an in-built face sealing 'O' Ring, eliminating the need for flange gaskets. The maximum allowable operating pressure is 16 bar(g), and a minimum back pressure of 0.3 bar is required to maintain valve tightness.
Material List: The body is made from materials such as ASTM A105, AISI304, AISI316, AISI316L, or Bronze. The disc is available in AISI304, AISI316, AISI316L, or Bronze. O-Rings and seals are made from EPDM, NBR, Viton, Silicone, or PTFE. Other components include washers and screws made from AISI316, and eye bolts from galvanized steel.
Dimensions and Weight: The document provides detailed dimensions and weights for each valve size, ranging from DN40 to DN600. For example, a DN40 valve has a net unit weight of 0.7 kg, while a DN600 valve weighs 130 kg.
Pressure Drop Curve: The document includes a pressure drop curve, which is essential for understanding the flow characteristics and performance of the valve under different pressure conditions.
