Specifications
Sanitary Pneumatic (Manual) Globe Valve / Stop Valve / Gate Valve
HS Code: 8481804090
TECHNICAL PARAMETERS:
1. Application:
The valves are widely used in automation and control systems to regulate pressure, flow, level, temperature, and tank levels. They ensure precise control and safe operation in various industrial environments.
2. Working Principle:
The pneumatic stop valve converts compressed air energy into mechanical movement, which drives the stem to move axially, allowing the sealing components to shift positions. This enables the opening or closing of the pipe outlet, controlling the direction of the medium or keeping it stationary. The manual version is operated via a handle, serving the same purpose of directing or stopping the flow of media.
3. Technical Data:
I. The new-style sanitary stop/switch valves offer improved safety, clearance, durability, and aesthetics.
II. A separate open support design isolates the pneumatic actuator from the valve body, allowing direct inspection of the shaft seal. This design prevents heat transfer from the valve body to the actuator.
III. "NC" and "NO" functions can be switched instantly.
IV. The spherical valve body ensures smooth fluid flow and minimal resistance.
V. The material processing is gentler, enhancing performance and longevity.
VI. Standardized valve body design offers flexible and varied connection styles.
VII. A metal stop mechanism ensures long-lasting seal integrity.
VIII. Quick and convenient assembly and maintenance make it user-friendly.
4. Materials:
Material contact parts: Stainless Steel 304 or 316L.
Valve core seal options:
a) Soft seals: EPDM (standard), SILICON, FDM, HNBR (optional).
b) Metal seals available upon request.
5. Advantages:
Seals: Excellent resistance to acids, alkalis, and high temperatures, with minimal permanent compression deformation.
Investment-forged valve plug: Pressure resistance up to 1.2 MPa, with better metallurgical structure than castings.
Design: Modern and stylish, aligned with international trends.
