CAST STEEL GATE VALVES
CAST STEEL GATE VALVES
KVC (UK) LTD Gate valves are manufactured to API Std.600 and tested to API Std.598
Gate Valves are the most commonly used shut-off valve in the industry today. They are used where minimum pressure drop
and bi-directional on-off service is required. Gate valves are not designed for throttling service. Prolonged use in the partially open position may lead to premature wear and damage to the seating surfaces.
Our standard offering has a rising stem with an outside screw and yoke.
