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 level. They ensure precise control of fluid or gas flow in various industrial settings.
 
2. Working Principle:
The pneumatic stop valve converts the energy from compressed air into mechanical movement, which drives the stem to move axially. This motion controls the sealing components, allowing the valve to open or close the pipe outlet, thus changing the direction of the medium or holding it in place. The manual version is operated by a hand lever, achieving the same purpose of controlling the flow or stopping it.

3. Technical Features:
I. New-style sanitary stop/switch valves offer improved safety, clearance, durability, and aesthetics.
II. A separate support design isolates the pneumatic actuator from the valve body, enabling direct inspection of the shaft seal. This design prevents heat transfer from the valve body to the actuator, enhancing performance and longevity.
III. The "NC" and "NO" functions can be switched instantly, providing flexibility for different applications.
IV. Spherical valve bodies provide ideal fluid dynamics and minimal resistance.
V. The materials used are more gentle on the process media, reducing wear and tear.
VI. Standardized valve body designs allow for flexible and diverse connection styles.
VII. A metal stop mechanism ensures long-lasting seal integrity.
VIII. Quick and convenient assembly and maintenance make these valves 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)
