Description of Stainless Steel Swing Check Valve:

ZECO is a professional manufacturer of swing check valves, stainless steel materials can be selected ASTM A351 CF8, ASTM A351 CF8M, ASTM A351 CF3, ASTM A351 CF3M, UNS S32205 or super stainless steel materials and so on. ZECO is very strict about the testing of raw materials. All stainless steel materials must undergo spectral testing and physical analysis when they arrive at the factory, and only when they meet the requirements of international standards can they be allowed to enter the factory and start the formal processing process. ZECO’s stainless steel swing check valve opens the disc fully in the line to prevent disc media flow and increase flow resistance.Swing check valve is the most important process requirements in the disc sealing surface and valve body sealing surface, because there is no external force to help seal, so only the disc and valve seat sealing surface can be closely matched to achieve the complete sealing state, at the same time, according to the requirements of the working conditions can change the material of the disc sealing surface to achieve the desired effect.

Stainless steel swing check valves are designed and manufactured strictly to International Standards API 6D, BS1868, ASME B16.34 or Equivalent, o reduce the flow resistance and pressure drop to the minimum possible extend, which is suitable to be mounted in horizontal position only, lapped and screwed in seat ring ensures tight shut of and long duration service. Valve’s disc is perfectly designed, accurately machined and guided for efficient automatic shut off at zero pressure, with a feature of compact structure & Low emission service. In both Swing & Piston Constructions.
