Z41X-16Q DN50-DN600 Open Stem Ductile Iron Gate Valve Large Diameter Soft Seal Cast Iron PN16 Sluice Valve Manufacturers

Purpose and Functions:

• 
  

  The rising stem elastic soft seal gate valve uses the overall rubber coating of the rising stem gate valve to produce deformation compensation to achieve a good sealing effect. It overcomes the phenomena of poor sealing, leakage and rust of general gate valves, and more effectively saves installation controls. The opening and closing part of the rising stem elastic gate valve is a gate valve. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.

• 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 slight deformation to improve its craftsmanship and compensate for the deviation of the sealing angle during the processing. This kind of gate It's called an elastic gate. This type of valve should generally be installed horizontally in the pipeline.

  
  

  
  

Design Standards:

• Design and production: API 600

• Structure length: ASME B 16.10

• Pressure test standard: API 698

• Connection flange dimensions: ASME B16.5

Valve Characteristics：

• The flat-bottomed valve seat prevents dirt from accumulating and makes the elastic seat softly seal the gate valve;

• The valve disc is entirely covered with nitrile rubber;

• The internal parts of the valve are made of stainless steel and copper alloy materials, which can be used in sewage systems to adapt to harsh working environments;

• Small size, light weight, easy to install and maintain;

• The valve stem is sealed with three O-rings, which greatly reduces the friction resistance during switching.
