Stainless steel Consolidated Vacuum Thermal Release Safety Valve

Stainless steel Consolidated Vacuum Thermal Release Safety Valve with pressure gauge is a sanitary valve made of SUS 304/316L stainless steel with a fully mirror-polished finish. It is typically installed on top of sanitary pipelines or tanks in the food and pharmaceutical industries to automatically relieve pressure in case of overpressure, while the pressure gauge monitors the pressure in real time.It offers quick-release clamps, butt welding connections, EPDM/PTFE seals, and spring-loaded or manually adjustable actuation methods. It ensures product hygiene and safety, mitigates compliance risks, reduces the frequency of seal replacement, lowers maintenance costs and material waste, and is suitable for various sanitary production processes.The difference between a sanitary stainless steel U-type water-sealed safety valve with a pressure gauge and a regular safety valve lies in its use of food-grade stainless steel and a fully mirror-polished design. It integrates a pressure gauge for real-time pressure monitoring, ensuring hygiene and safety while mitigating compliance risks. Joneng Valves' products further utilize more durable food-grade sealing rings, reducing replacement frequency. The U-type water-sealed structure facilitates maintenance, lowers costs, and is more suitable for various sanitary processes, making it a more worthwhile choice for customers.

Stainless steel Consolidated Vacuum Thermal Release spring loaded Safety Valve with pressure gauge consists of a valve body, U-shaped water seal chamber, pressure gauge, valve core, spring, and sealing ring. It connects to sanitary pipelines using quick-release clamps. After installation, it can stably maintain system pressure, prevent overpressure, and eliminate leakage and backflow. Its working principle is as follows: when the system pressure exceeds the set value, the medium pushes the valve core to open and release pressure; it automatically closes after the pressure recovers, with the pressure gauge monitoring in real time. Manual, pneumatic, and electric adjustment options are available. The structure has no dead angles, ensuring stable sealing, guaranteeing product hygiene and safety, mitigating compliance risks, reducing the frequency of sealing ring replacement, lowering maintenance costs and material waste, and adapting to various sanitary production processes.water seal exhaust valve

  • A:The material is pure, corrosion-resistant, and does not leach heavy metals. It has high structural strength and will not deform or contaminate the medium during long-term use.
  • B: Ensuring product hygiene and safety from the source, meeting the high-cleanliness requirements of industries such as pharmaceuticals, food, and beverages, easily passing GMP, HACCP, and other compliance audits, and mitigating compliance risks.
  • 2. Processing technology
  • F:The product is manufactured using a one-piece precision casting and fully welded molding process. The inner cavity and flow channels are treated with mechanical polishing and electrolytic polishing, resulting in a surface roughness Ra ≤ 0.4 μm.
  • A: Seamless construction with no cleaning dead spots; can withstand CIP online cleaning and SIP online sterilization.
  • B: Completely eliminates bacterial growth and media residue, reduces cleaning difficulty, and improves production cleanliness.
  • 3. Structural features
  • F: U-shaped water-sealed spring micro-opening structure, integrated pressure gauge for real-time monitoring, supports quick-connect Tri-Clamp connection, and includes a pressure setting device.
  • A: Compact size, flexible installation, precise pressure response, visual monitoring, and easy assembly/disassembly.
  • B: Adaptable to sanitary pipelines with limited space, provides real-time monitoring of operating conditions, offers rapid pressure relief protection, and ensures continuous production.
  • 4. Features of main components
  • F: The valve core is precision-ground from SUS 316L stainless steel to achieve a high-precision fit with the valve seat; the spring is made of corrosion-resistant stainless steel.
  • A:The valve core opens and closes smoothly, is wear-resistant and erosion-resistant, has good repeatability, and maintains stable accuracy over long-term operation.
  • B:Extends the overall lifespan of valves, reduces downtime due to malfunctions, and lowers maintenance costs and material waste.
  • 5. Features of the sealing ring
  • F:Uses food-grade EPDM, silicone, or PTFE one-piece molded sealing rings, compliant with FDA and USP Class VI certifications.
  • A: The sealing surfaces fit tightly, are resistant to high temperatures, acids and alkalis, and aging, and are not easily deformed or swollen.
