Manual/Actuator Extension Stem Gate Valve for Medium Temperature Media
An extension stem gate valve is a type of valve that has a longer stem than a traditional gate valve. This allows the valve to be installed in deep and hard-to-reach places, such as underground or in confined spaces. The extension stem also provides a longer lever arm, which makes it easier to operate the valve.
Extension stem gate valves are typically made of steel or stainless steel and can be used with a variety of fluids, including water, oil, and chemicals. They are available in a variety of sizes and materials to meet the specific requirements of each application.
Extension stem gate valves operate by rotating the valve stem. As the stem rotates, the gate moves up or down, opening or closing the flow of fluid. Extension stem gate valves can be operated manually, using a handwheel or wrench, or they can be automated using electric or pneumatic actuators.
Extension stem gate valves are a reliable and versatile type of valve that can be used in a wide range of applications. They are a good choice for applications where the valve needs to be installed in a difficult-to-reach location or where a longer lever arm is needed for easier operation.
The resilient seat on this valve provides a good seal against the body, even when under high pressure or temperature fluctuations. This makes it suitable for applications with potentially hazardous leaks. The ductile iron body also provides excellent corrosion resistance, allowing it to be used even in harsh chemical or environmental conditions.
The flange end is simple to install and attach to other piping components, while the extended stem makes it easier to operate. The ductile iron body and stainless steel stem are both strong and durable, making the valve a good option for long-term, consistent use.
The body of the valve is made of ductile iron, which is a strong and durable material that is resistant to corrosion. It is manufactured to the ANSI/AWWA C500-19 standard, which specifies the dimensions and tolerances of ductile iron valves. The face-to-face dimension, which is the distance between the faces of the flanges on the valve, is important for ensuring that the valve can be properly aligned with the piping system. The flange rating is the maximum pressure that the valve can withstand and is determined by the thickness and material of the flanges. The end connections of the valve can be flanged, threaded, or welded and are important for connecting the valve to the piping system.
The seat of the valve is made of rubber, which is a soft and flexible material that provides a good seal against the valve body. The stem of the valve is made of stainless steel, which is a corrosion-resistant material. The stem is extended, which provides a longer lever arm for easier operation. The operating temperature and operating pressure are the maximum temperature and maximum pressure that the valve can withstand, respectively. They are determined by the materials used in the construction of the valve and the design of the valve.

1.hat is the maximum temperature rating for this valve?
The standard valve is rated for up to 800°F. Higher temperature ratings up to 1500°F are available on request.2.What materials are used in this valve?
Standard materials are carbon steel body, 400 series stainless steel trim, graphite packing, and viton gaskets. Other exotic alloys are available for higher temperatures.3.How is the packing adjusted to prevent leakage?
The valve has a bolted bonnet and packing gland. Tightening the gland nut compresses the packing and prevents leakage. The packing can be replaced without removing the bonnet.4.What are the end connection choices?
Threaded, socket weld, butt weld, and flanged ends are available. Rating and facings can be specified as needed.5.What are the actuator options for remote operation?
Pneumatic, hydraulic, and electric actuators can be supplied. Control accessories like positioners, solenoid valves can also be provided.6.What maintenance is required?
Periodic tightening of the packing gland to stop leaks. Checking for smooth operation of the valve. Re-greasing stem threads. Packing replacement after extended use.7.Is valve customization available?
Yes, we can customize materials, connections, actuators, and additional options to suit the application requirements..Send your inquiry directly to us
