Specifications:

Sanitary Pneumatic (Manual) Globe Valve / Stop Valve / Gate Valve

HS Code: 8481804090


TECHNICAL PARAMETERS:

1. Application:

These valves are widely used in automation and control systems to regulate pressure, flow, level, temperature, and tank levels. They ensure precise control of the medium in various industrial processes.

2. Working Principle:

The pneumatic stop valve converts the energy from compressed air into mechanical movement, which drives the stem to move axially, thereby controlling the opening or closing of the pipe. This allows for directional changes or retention of the medium. The manual version is operated via a handle and serves the same purpose—controlling the flow direction or stopping the medium.

3. Technical Data Sheet:

I. New-style sanitary stop/switch valves offer enhanced safety, clearance, durability, and aesthetics.

II. A separate support system isolates the pneumatic actuator from the valve body, allowing direct inspection of the shaft seal. This design separates the gears from the product parts, preventing heat transfer from the valve body to the pneumatic device.

III. "NC" and "NO" functions can be switched instantly.

IV. Spherical valve bodies provide ideal fluidity and minimal resistance.

V. The material processing is gentler, ensuring better performance and longevity.

VI. Standard valve body design offers flexible and diverse connection styles.

VII. A metal stop mechanism ensures long-lasting sealing performance.

VIII. Quick and convenient assembly and maintenance make it user-friendly.

4. Material:

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:

Excellent acid and alkali resistance, high-temperature performance, and minimal permanent compression deformation. Forged valve plugs provide superior pressure resistance and better metallurgical structure than castings. Aesthetically designed to match international trends. High cost-performance ratio with reliable operation and reduced costs compared to imported alternatives.

6. Connection Types:

Welded, Clamped, Screw or Threaded, Welded-Screw, Flange

To ensure compatibility with imported equipment, all connection styles are made according to international standards such as DN11850, IDF/ISO, SMS 3A.

7. Sizes:

  1. DIN: DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100
