Advantages of Industrial High Temperature Angle Seat Valve:

1. high-temperature resistance

   • medium temperatureCovering -20 ℃ to+300 ℃ (high-temperature type), it can stably handle high-temperature media such as steam and hot oil.

   • Sealing technologyAdopting PTFE V-ring and spring compensation structure to ensure sealing reliability at high temperatures and prevent leakage.

   • Material selectionThe valve body is made of 316L stainless steel, and the actuator housing is made of PPS (polyphenylene sulfide) or stainless steel, suitable for high temperature environments.

2. High flow and low flow resistance

   • Corner seat structureThe right angle flow channel design reduces eddy currents and dead zones, with lower flow resistance than ordinary globe valves and a flow rate increase of over 30%.

   • Datong diameterSupports DN15-DN125 diameters to meet the needs of large-scale fluid transportation.

3. Fast response and long lifespan

   • pneumatic actuatorSingle acting (spring reset) or double acting (air pressure control) design, response time ≤ 0.5 seconds, suitable for frequent start stop conditions.

   • Self-lubricating materialPTFE seals reduce wear and have a lifespan of over 1 million cycles.
