Small-Bore Fabricated GROVE
Through-conduit and double block-and-bleed functionality.
60 years of worldwide service in oil, gas, chemicals, water, slurry, and multiproduct applications has established the Pow-R-Seal double expanding gate valve as one of the most trusted gate valves, especially where safety and seal reliability are critical.
The positive, mechanical seating force of the lock-in-place seals holds with zero leakage through conditions of vibration, pressure change, and temperature excursion. The rigid, cast steel body resists pipeline bending moments.
TFE seals on both faces of the valve provide drop-tight sealing even at low differential pressure, while metal-to-metal contact between the seals and gate mechanism provides fire-safe shutoff. Optional all-metal seals also are available for service up to 1,000 degF [538 degC], where leakage rates comply with API Spec 6D, Supplement 2.
Our Pow-R-Seal gate valve is the choice of liquid pipeline operators because it tolerates the wax, paraffin, abrasives, and multiproduct flow that causes problems in other valve designs.
The gate valve provides these specific advantages resulting in reliable performance and long life:
The WKM Pow-R-Seal gate valve provides these specific advantages resulting in reliable performance and long life:
Installation, operation, and maintenance manual.
High-quality, through-conduit, expanding gate valves engineered for performance in critical isolation applications where a tight mechanical seal that is normally unaffected by pressure variations and vibrations is needed.
Save space, reduce the need for multivalve systems, and achieve zero leakage.
Stop, allow, or throttle the flow of process fluid with very low friction loss.
