BZ41H, BZ41W, BZ41Y PN16~PN40 insulated jacket wedge gate valves: manual, flange connected, rising stem wedge rigid single gate valve, valve seat sealing surface material is alloy and stainless steel, nominal pressure PN16~PN40, valve body material is carbon steel, chromium nickel molybdenum titanium stainless steel, with insulation function gate valve. Mainly used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc., it can maintain insulation and prevent medium crystallization, in order to transport high viscosity media that will solidify at room temperature.
Product characteristics
1. The jacket is welded between the two flanges of the valve, and the side and bottom of the valve are provided with a connecting port of the jacket.
2. The connection flange size is larger than the connection flange of the ordinary valve of the same specification to two specifications, and the structural length is the same as that of the ordinary valve of the same specification.
3. The jacket can flow freely through steam or other hot insulation medium to ensure that the viscous medium can flow smoothly through the valve.
