Dn25 Sanitary Pressure Relief Valves with Union Type Check Valve

**Product Name:** DN25 Sanitary Pressure Relief Valve with Union Type Check Valve **Model No.:** XS-VALVE00300 **Sealing Material:** Food Grade Rubber **Operating Temperature Range:** -10°C to +120°C **Medium Type:** Liquid and Gas **Surface Finish:** Ra 0.8µm **Trademark:** XUSHENG **Certifications:** ISO, 3A, SGS, CE **Origin:** Wenzhou City, Zhejiang Province, China **HS Code:** 8481804090 --- ### **Application** Our company specializes in producing a wide range of safety valves, adjustable valves, and check valves designed for hygienic applications. These valves are widely used in the food, beverage, dairy, and pharmaceutical industries where cleanliness and safety are critical. --- ### **Technical Parameters** | **Parameter** | **Specification** | |-----------------------------|--------------------------------------------| | Working Pressure | ≤6 bar | | Pressure Control Range | 0.5 – 6 bar | | Operating Temperature | -10°C to +120°C | | Medium | Liquid and Gas | | Sealing Material | Food Grade Rubber | | Material Quality | SS304, SS316L | | Connection Standards | DIN, 3A, SMS, ISO | | Connection Ends | Male ends, Tri-clamp, Welded ends | | Surface Treatment | Ra 0.8µm | --- ### **Working Principle** The pressure relief valve is designed to regulate system pressure by adjusting the spring compression nut. This allows it to set a specific maximum pressure level to prevent equipment damage. Under normal operating conditions, the valve remains closed. When the system pressure exceeds the set limit, the valve opens automatically to release excess pressure. It also facilitates CIP (Cleaning in Place) for the valve and piping systems, ensuring hygiene and efficiency. To ensure accurate performance, the valve is calibrated under strict standards. For optimal operation, it's recommended to match the working conditions as closely as possible to real-world scenarios. --- ### **Key Advantages** 1. **Simple Design & Easy Maintenance:** The compact structure makes it easy to adjust pressure and maintain. 2. **Adjustable Pressure Range:** Allows precise control within the safety limits. 3. **Hygienic Materials:** Made from stainless steel (SS304/SS316L), with a bright and clean surface. The food-grade rubber seal ensures compliance with sanitary standards. 4. **Prevents Backflow:** Installation must follow correct flow direction to avoid fluid reversal. --- ### **After Sales Service** - **Warranty Period:** 1 year (excluding wear parts; free replacement during warranty period). - **Technical Support:** Free training on machine usage and repair services. --- ### **Packing & Shipping** - **Port:** Shanghai or Ningbo, China - **MOQ:** 1 Set - **Supply Capacity:** 1,000 sets/month - **Payment Terms:** T/T, Western Union, PayPal, L/C - **Packaging:** Shrink-wrapped in seaworthy wooden cases - **Delivery Time:** Varies based on order quantity - **Shipping Methods:** By sea, air, or express --- ### **About Us** Wenzhou Xusheng Machinery Industry Co., Ltd. is a professional manufacturer specializing in designing, developing, and manufacturing hygienic valves, pipe fittings, pumps, and tanks.
