The product adopts ASTM A105 forged steel valve body, combines 1500LB high-pressure grade and phosphating surface treatment technology, and is equipped with a metal hard sealing system. It provides reliable cut-off service in high-temperature, high-pressure and corrosive environments, and is an ideal choice for industries such as petrochemical and power energy.

Technical specifications

Product features

1. High-pressure phosphating anti-corrosion technology

Surface phosphating treatment

A dense phosphate protective layer is formed, and the corrosion resistance is enhanced by three times

The surface hardness has been significantly enhanced and it has excellent wear resistance

Provide an ideal substrate for subsequent coatings and enhance adhesion

Comprehensive protection system

Phosphating layer thickness: 8-15μm

Salt spray test: No red rust after ≥500 hours

Comply with the requirements of ISO 9717 standard

2. Class 1500 high-voltage design

Ultimate pressure resistance capacity

Design pressure: 25 MPa

Shell test pressure: 37.5 MPa

Sealing test pressure: 27.5 MPa

High-pressure optimized structure

Design for thickening the valve body wall thickness

Strengthen the valve stem drive system

Enhanced bearing structure

3. Metal hard seal system

Super-hard sealing surface

Spherical sealing surface: Supersonic sprayed tungsten carbide, hardness HRC ≥ 65

Valve seat sealing surface: Stellite alloy, hardness HRC ≥ 58

High-temperature adaptability

Maintain stable sealing at a high temperature of 425℃

Matching design of thermal expansion coefficient

Long-life design

The sealing life is ≥ 20,000 cycles

The wear resistance is 5 to 8 times that of soft seals

4. Floating ball high-pressure seal

Self-reinforcing seal: The medium pressure pushes the ball to press against the valve seat. The higher the pressure, the more reliable the seal

Bidirectional blocking: The carefully designed preload ensures reliable bidirectional sealing

Low flow resistance design: Full bore structure minimizes pressure loss

5. Safety protection design

Fire safety: Passed the API 607 fire test

Anti-static design: The resistance between the ball, valve stem and valve body is less than 10 Ω

Anti-blowout valve stem: T-shaped structure design to ensure safe high-pressure operation
