Pacific® 螺栓阀盖型铸钢闸阀
Pacific闸阀是当今工业中最常用的切断阀。
它们使用在需要最小压降和双向切断的场合。闸阀不能用于节流工况。在阀位部分开启的情况下长时间使用，常常会损伤阀座表面。闸阀可以配置多种结构型式的楔形阀板（实心、弹性和分体），以更好地满足特定的工况条件。
Pacific闸阀通常是手轮操作，但也提供齿轮箱、电动执行机构，或气缸（气动或液压）执行机构以实现远程操作。
Pacific® Bolted Bonnet Cast Steel Gate Valves
Gate valves are the most commonly used shutoff 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 will generally damage seating surfaces. Gate valves are available with a number of wedge configurations (solid, flexible and split) to best meet the specific service conditions.
Gate valves normally are handwheel operated, but are also available with gearing, electric motor actuators, or cylinder (pneumatic or hydraulic) actuators for remote operation.
