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 are ideal for industries such as food processing, pharmaceuticals, and biotechnology where hygiene and precision are critical.

2. Working Principle:

The pneumatic stop valve converts the energy from compressed air into mechanical movement, which drives the stem to move axially. This action controls the sealing components, allowing the valve to open or close, thus regulating the direction of the medium or keeping it in place. The manual version is operated via a handle, serving the same purpose of controlling the flow and direction of the medium.

3. Technical Features:

I. New-style sanitary stop/switch valves offer enhanced safety, clearance, durability, and aesthetics. II. A separate support design allows direct inspection of the shaft seal, separating the actuator from the valve body and preventing heat transfer. III. Instant switching between "NC" and "NO" functions. IV. Spherical valve bodies ensure smooth fluidity and minimal resistance. V. Improved material handling with reduced wear and tear. VI. Standardized valve body design provides flexible joint styles. VII. Metal stop mechanisms ensure long-lasting seal performance. VIII. Quick and easy assembly and maintenance.

4. Materials:

Material contact parts: Stainless Steel 304 or 316L. Seal options: a) Soft seals: EPDM (standard), Silicon, FKM, HNBR (optional). b) Metal seals available upon request.

5. Advantages:

Excellent acid and alkali resistance, high-temperature performance, and low permanent compression deformation. Investment-forged valve plugs provide superior pressure resistance (less than 1.2 MPa) and better metallurgical structure compared to castings. Modern design aligns with international trends. Cost-effective solution with reliable performance, suitable for replacement of imported alternatives.

6. Connection Types:

Welded, Clamped, Screw/Threaded, Flanged. All connection styles are designed to meet international standards such as DN11850, IDF/ISO, SMS 3A for seamless compatibility with imported equipment.

7. Sizes:

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