Pacific? 螺栓閥蓋型鑄鋼閘閥
Pacific閘閥是當(dāng)今工業(yè)中常用的切斷閥。
它們使用在需要小壓降和雙向切斷的場(chǎng)合。閘閥不能用于節(jié)流工況。在閥位部分開啟的情況下長(zhǎng)時(shí)間使用，常常會(huì)損傷閥座表面。閘閥可以配置多種結(jié)構(gòu)型式的楔形閥板（實(shí)心、彈性和分體），以更好地滿足特定的工況條件。
Pacific閘閥通常是手輪操作，但也提供齒輪箱、電動(dòng)執(zhí)行機(jī)構(gòu)，或氣缸（氣動(dòng)或液壓）執(zhí)行機(jī)構(gòu)以實(shí)現(xiàn)遠(yuǎn)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.
