Food Grade Ss304/Ss316 Stop Valve, Global Valve

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 are ideal for use in the food, pharmaceutical, and biotechnology industries where hygiene and safety are critical.

2. Working Principle:

The pneumatic stop valve converts the energy from compressed air into mechanical motion, which drives the stem to move axially. This movement controls the position of the sealing components, allowing the valve to open or close, thus controlling the direction or stopping the flow of the medium. The manual version is operated via a handle, achieving similar functions by manually adjusting the valve position.

3. Technical Data:

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 shaft seal inspection. This design also separates the gears from the product parts, preventing heat transfer from the valve body to the actuator.
III. Instant switching between "NC" (Normally Closed) and "NO" (Normally Open) functions.
IV. Spherical valve body ensures smooth fluid flow and minimal resistance.
V. Material handling is more gentle, reducing wear and tear.
VI. Standardized valve body design allows for flexible and diverse joint styles.
VII. Metal stop mechanism guarantees long-lasting seal performance.
VIII. Quick and convenient assembly and maintenance process.

4. Materials:

Materials in contact with the medium: Stainless Steel 304 or 316L
Seal options:
a) Soft seals: EPDM (standard), Silicon, FDM, HNBR (optional)
b) Metal seals

5. Advantages:

Excellent acid and alkali resistance, high-temperature performance, and low permanent compression deformation. Investment-forged valve plug offers better metallurgical structure than cast ones, with pressure durability below 1.2MPa. Sleek, modern design aligned with international trends. Cost-effective solution with reliable operation and potential for import substitution.

6. Connection Types:

Welded, Clamped, Screw or Threaded, Flange. To ensure compatibility with imported equipment, all connection styles are designed to meet international standards such as DN11850, IDF/ISO, SMS 3A.
