- Design: In Accordance with Section 5 of API 6H Spec.
- Shear-Pin Breakaway: Designed to Breakaway at Factory-set up 275 PSIG (18.8 Bar) for Class 150.
Higher strength shear-pins available up to 430 PSIG (30 Bar) for Class 150 & 1110 PSIG (76 Bar) for Class 300.
Actual breaking of shear-pins are designed considering Pull-away Force and Internal Operating Pressure. - Seals: Viton®, Buna-N, Teflon® (PTFE), Silicon, EPDM, and Neoprene. Viton® & Teflon® regd. Trade-mark of DuPont.
- Temperature Range: For seal material Buna-N -40°F to 250°F, Viton® -20°F to 400°F,
Teflon® (PTFE) -60°F to 550°F. For low or high temp. applications, contact factory. - Hydro-Testing: Each Half separately internally Hydro-tested as per API 6H Specs.
For ANSI Class 150 (tested at 430 PSIG = 30 Bar) and
For ANSI Class 300 (tested at 1110 PSIG = 76 Bar) at shop before shipping. - Shear-Pin Breakaway Testing: Fully Assembled Breakaway Test at 275 PSIG (18.8 Bar) for ANSI Class 150
and 700 PSIG (48 Bar) for ANSI Class 300 or as agreed. - Functional Flow Testing: Fully Assembled Functional Flow Tests are available and conducted during R&D.
A Third-Party (BVIS/equal) witnessing Hydro-test, Breakaway test & Functional flow-test report, available. - Easy to REASSEMBLE in the field using FREE spare shear-pins, supplied with Installation Instruction.
