Unloading Valve with soft seat

Performance Features

• Enhanced Sealing Capabilities: The soft seat design allows for a tighter seal than metal-to-metal contact, minimizing leakage even under varying pressure conditions .
• Flexibility and Compressibility: The elastomeric material conforms to the mating surfaces, providing a flexible and compressible interface that enhances sealing effectiveness .
• Resistance to Wear and Tear: The soft seat is less prone to wear and tear compared to hard seat valves, ensuring long-term reliability and reduced maintenance costs .

Advantages

• Superior Sealing Performance: The soft seat valve provides a tighter seal, making it ideal for applications where backflow must be strictly prevented .
• Suitability for Cleanliness-Sensitive Applications: The smooth surfaces of the elastomeric seals reduce the risk of fluid contamination, making it suitable for industries such as food and beverage processing, pharmaceuticals, and semiconductor manufacturing .
• Easy Cleaning and Sanitization: Soft seat valves can be designed for easy cleaning and sanitization, further enhancing their suitability for hygienic applications .

Application Scenarios

• Food and Beverage Processing: Soft seat valves are ideal for maintaining the purity of fluids in food and beverage production lines .
• Pharmaceutical Manufacturing: The valves are used to ensure the integrity of pharmaceutical fluids, preventing contamination and ensuring product quality .
• Semiconductor Manufacturing: Soft seat valves are used in semiconductor fabrication processes to maintain the purity of chemicals and gases .
• Hydraulic and Pneumatic Systems: These valves are used to control the flow of hydraulic fluids and compressed air in various industrial systems .

Technical Specifications

• Flow Capacity: Up to 1200 GPM (455 LPM) with 3600 PSI (250 Bar) .
• Operating Pressure: Designed to operate with low viscosity fluids and raw water working pressure .
• Temperature Range: The elastomeric materials used in soft seat valves may have limitations regarding temperature and pressure, so users must carefully evaluate the operational parameters of their applications .
• Materials: The valve body is typically made of stainless steel or brass, while the soft seat is made of elastomeric materials such as rubber or nitrile .

Maintenance

• Regular Inspections: Conduct regular visual inspections to identify any signs of leakage or corrosion around the valve body and connections .
• Seal Inspection: Regularly inspect the elastomeric seals for signs of wear, cracking, or degradation, as these can lead to leakage .
• System Checks: Monitor the fluid flow and pressure to identify any changes that could indicate valve performance issues. Address any abnormalities promptly .
• Avoid Over-Tightening: When installing soft seat valves, avoid over-tightening the connections, as excessive pressure can damage the elastomeric seal .
• Debris Inspection: Before installation, inspect the valve and the connecting pipes for any debris or contaminants that could compromise sealing .
