Describe
Product Usage
 
BZ41H, BZ41W, BZ41Y type PN16~PN40 insulation jacket type wedge gate valve: manual, flange connection, open rod wedge type rigid single gate, valve seat sealing surface material is alloy and stainless steel, nominal pressure PN16~PN40, valve body The material is carbon steel (BZ41H-16C~BZ41H-40 BZ41Y-16C~BZ41Y-40), chrome-nickel-titanium stainless steel (BZ41W-16P~BZ41W-40P BZ41Y-16P~BZ41Y-40P), chrome-nickel-molybdenum-titanium stainless steel (BZ41W- 16R~BZ41W-40R BZ41Y-16R~BZ41Y-40R), gate valve with heat preservation function. It is mainly used in various systems such as petroleum, chemical, metallurgy and pharmaceutical. It can keep warm and prevent crystallization of medium to transport high viscosity medium which will solidify at normal temperature.
 
Features
 
1 The jacket is welded between the two flanges of the valve, and the connecting port of the jacket is arranged on the side and the bottom of the valve.
 
2 The connection flange size is one to two specifications larger than the connection flange of the common valve of the same specification, and the structural length is the same as that of the ordinary valve of the same specification.
 
3 The jacket can freely flow through steam or other hot insulation medium to ensure that the viscous medium can flow smoothly through the valve.
