  • 2-way positive shut off and 3-way directional control of fluids in process, power and instrument application.
  • Valves are designed to control fluids in full open or full closed position.
  • Valves that have not been actuated for a period of time may have a higher initial actuation torque.
  • Valves must be in open position during system test not to damage the valve seat.
  • Sour Gas Service NACE MR0175 available.

Cleaning and Packaging

Every valve is cleaned and packaged in accordance with DK-LOK cleaning standard DC-01. Special cleaning and packaging in accordance with DK-LOK DC-11 ensures compliance with product cleaning of ASTM G93 Level C is available for valves with PCTFE seat.
