Where to use soft seal gate valve

Soft seal gate valves are best suited for applications where tight shutoff is critical and the pressure and temperature are within the limits of the soft sealing material. Here’s a detailed breakdown:

1. Typical Fluids / Media

• Water: Drinking water, wastewater, cooling water systems

• Oils: Lubricating oil, light industrial oils

• Gases: Natural gas, air, low-pressure steam (if compatible with soft seal)

• Chemicals: Non-abrasive chemicals compatible with PTFE or rubber

• Other non-abrasive fluids: Any fluid where leakage must be minimized

2. Pressure & Temperature Range

• Pressure: Usually up to 16–25 bar (depends on valve design)

• Temperature: Typically –20°C to 180°C for PTFE or similar polymers

• Not suitable for very high-pressure systems or high-temperature steam above 200°C

3. Applications / Industries

1. Water and Wastewater Treatment

• Distribution pipelines, pumps, and reservoirs

2. Oil & Gas

• Low-pressure fuel lines, pipelines for non-corrosive oil

3. Chemical Industry

• Non-abrasive chemicals like acids, alkalis, and solvents

4. HVAC Systems

• Heating, ventilation, and cooling pipelines

5. Food & Beverage Industry

• Soft seal materials like PTFE are often approved for sanitary use

4. Why Choose Soft Seal Here

• Provides bubble-tight shutoff, preventing leaks

• Easier to operate and maintain than hard seal

• Suitable for non-abrasive fluids

• Cost-effective for low-pressure systems
