Product details

Blocking valve structure Description:
 1, the valve is welded, straight channel without shrinking, single plane seal, valve sealing surface heap austenitic stainless steel, block plate with O-shaped rubber seal. 
 2, the use of self-tight cavity pressure seal structure, hydraulic test or operation, can be sealed by the medium pressure to achieve a reliable seal, and the higher the pressure, the more reliable the seal. 
 3, the valve body is made of high quality cast steel, both ends processed into U-groove and pipe directly butt welding, chemical composition and properties of the two materials are similar, excellent welding performance, without intermediate welding transition section; four open-loop 38CrMoAlA corrosion Nitriding, to ensure that its heat-resistant, and wear-resistant, corrosion-resistant, scratch-resistant, easy disassembly; cavity self-sealing gaskets, high temperature steam corrugated asbestos gaskets, 18-8 wire braided internal enhancements to ensure that the seal, Extend the service life; sealing surface surfacing 1Cr18Ni9Ti, rust, erosion, repeated tests can still guarantee the seal.
