Robust Valve Stem for Reliable Operation in High-Pressure Systems

Main Features

High strength and durability: The valve stem is made of high-strength alloy steel, stainless steel or other wear-resistant materials, which can withstand high pressure, high temperature and other harsh conditions to ensure long-term use without deformation.

• Corrosion resistance: The material of the valve stem is specially treated or surface coated, which has excellent corrosion resistance and is suitable for chemical, petroleum, natural gas and other industries.

• High-precision machining: The surface of the valve stem is precision machined to ensure a good fit with the valve body and seat, reduce wear and improve sealing performance.

• Various specifications and designs: According to different types of valves, various specifications, lengths and shapes of valve stems are available to meet various application requirements.

Common Specifications

Valve stems are available in various specifications and designs, and the common ones are:

• Rotary valve stem: Suitable for ball valves, butterfly valves and other rotary valves, to realize switching and regulation through rotary operation.

• Lifting valve stem: Suitable for globe valves, gate valves, through the lifting and lowering movement to control the spool position, to realize the on and off of the fluid.

• Telescopic valve stem: Suitable for valve stem design that needs to be adjusted in length in special environments.

Recommendations for Use

1. When installing the valve stem, make sure the precision of the fit between the stem and the valve body and spool to avoid loosening or abrasion affecting the sealing of the valve.

2. Regularly check the surface condition of the valve stem, especially in high temperature, high pressure or corrosive environment, and replace it in time when it is found to be worn or corroded.

3. Avoid excessive force when operating the valve stem to prevent deformation or damage to the valve stem.

Valve stems are widely used in various types of valves and industrial systems, including:

• Oil and gas industry: Used in wellhead units, pipeline valves and other critical equipment to ensure the control and safety of oil and gas flow.

• Chemical industry: Used in chemical reaction equipment to control the flow of corrosive media, requiring high corrosion resistance.

• Electric power: Used for steam and cooling water control in boilers, condensers and other systems in power plants.

• Water treatment system: Used for valve control in water treatment equipment to ensure the normal operation of the system.

• Marine: Used for valve control in marine engines and piping systems, requiring high corrosion resistance and durability.
