Z41W-25P GB Metal Gate Valve , Flange Gate 3 Inch Stainless Steel Gate Valve

Metal Gate Valve Z41W-25P GB stainless steel flange gate valve 304

specification

The opening and closing member of the gate valve is a gate. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted and throttled. The gate has two sealing faces. The two sealing faces of the most common mode gate valves form a wedge shape. The wedge angle varies with the valve parameters, usually 50, and is 2°52' when the medium temperature is not high. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce a small amount of deformation to improve its processability and compensate for the deviation of the sealing surface angle during the machining process. The board is called a resilient shutter. Stainless steel gate valve material is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve

First, the main outline of Z41W stainless steel gate valve:

The high and medium pressure stainless steel flange gate valve is suitable for cutting and connecting the pipeline medium on the pipelines of various systems of petroleum, chemical, hydraulic and thermal power stations with nominal pressure PN1.6～16.0MPa and working temperature ≤-29°C～550°C.
Applicable medium: water, oil, steam, and acid, alkali, ammonia, urea, sulfur-containing natural gas, etc.

Second, Z41W stainless steel gate valve structure features:

1. The selection of materials is in line with relevant domestic and international standards, and the overall quality of materials is high.
2. It meets the requirements of advanced standards at home and abroad, with reliable sealing, excellent performance and beautiful appearance.
3. The sealing pair is advanced and reasonable. The sealing surfaces of the ram and the valve seat are made of Stellite cobalt-based hard alloy with different hardness. The sealing is reliable, high hardness, wear resistance, high temperature resistance and corrosion resistance. Good anti-scratch performance and long life.
4. The valve stem is quenched and tempered and surface nitrided, which has good corrosion resistance, scratch resistance and wear resistance.
5, the use of wedge-type elastic ram structure, medium and large caliber thrust bearing, small friction, and equipped with impact hand wheel, easy to open and close.
6, can use a variety of piping flange standards and flange sealing surface form to meet various engineering needs and user requirements.
