The triple offset design ensures that the disc is away from the seat at a certain angle, thus reducing friction and wear during operation.
Made of WCB (A216) carbon steel, it has excellent mechanical strength, pressure resistance and durability.
Enables it to withstand high temperatures and ensure reliable sealing under extreme conditions.
The design complies with API 607 and API 6FA fireproof standards. In the event of a fire, the valve maintains a reliable seal to prevent the spread of hazardous media.
Due to the sturdy structure and metal sealing system, the valve can withstand high temperatures and high pressures, making it suitable for steam, oil, gas and other high-energy systems.
The triple offset design reduces the friction between the disc and the seat, requiring lower operating torque.
The valve is available in nominal sizes from DN40 to DN1600, with standard pressure ratings encompassing PN10, PN16, CL150, JIS 5K, and JIS 10K.
The face-to-face standard conforms to API609, BS5155, DIN3202, and ISO5752. Connection standards support PN6, PN10, PN16, PN25, 150LB, JIS 5K, 10K, 16K, and GOST33259, while the upper flange complies with ISO 5211.
The triple offset geometry prevents seat rubbing by lifting the disc away from the seat during operation, significantly decreasing friction, seat wear, and operating torque. The metal-to-metal seating system ensures reliable performance under high temperatures and high pressures.
Yes, the structural design strictly conforms to API 607 and API 6FA fireproof standards, ensuring an effective, reliable seal is maintained even during fire emergency conditions to halt hazardous media leakage.
Body materials include Cast Iron (GG25), Ductile Iron (GGG40/50), Carbon Steel (WCB A216), Stainless Steel (SS304/SS316/SS304L/SS316L), Duplex Stainless Steel (2507/1.4529), Bronze, and Aluminium Alloy. Discs are offered in matching alloys as well as coated options with Epoxy, Nylon, EPDM, NBR, PTFE, or PFA.
The valve can be configured with manual Hand Lever or Gear Box controls, as well as automated Electric Actuators or Pneumatic Actuators via its ISO 5211 upper flange.
