Description 描述

• Eliminates uncontrolled movements of the actuator in case of line rupture.消除了在線破裂，致動(dòng)器控制運(yùn)動(dòng),。 They are commonly applied with dead weight cylinders.它們通常適用,，自重汽缸。
• Volume limiting flat seat valves.成交量單位所在地限制閥,。
• At normal flow, the poppet is held open by a spring with enough force to counteract the force on the poppet created by the flow.在正常流動(dòng),，小鬼是一所具有足夠的力量彈開，以抗衡的流動(dòng)所帶來的小鬼的力量,。
• When the supply line is ruptured, the flow from 2 to 1 exceeds the specified flow rate, the P across the poppet creates a force greater than the spring force and closes the valve.當(dāng)電源線斷裂,，從2比1流量超過的流量,，對面的小鬼P創(chuàng)建一個(gè)力量比彈簧力更大，關(guān)閉閥門,。 This closing flow rate is adjustable. The valve opens automatically by pressurizing connection 1.這收盤流量可調(diào),。閥門打開自動(dòng)加壓連接1。
• Depending on the pressure P, the leakage rate through the valve is approximay 0 to 6 in3 min.根據(jù)不同的壓力P,，通過閥門的泄漏率約為0六立方英寸分鐘,。 If this is excessive, the valve threads can be sealed and made leak-free.如果這是過度，閥門線程可以加以密封,，使無泄漏,。
• Installed between actuators and possible line breakage points.安裝和可能的執(zhí)行機(jī)構(gòu)之間的線路破損點(diǎn)。
• A cartridge-type valve can be installed into an actuator port.彈筒型閥可以安裝到一個(gè)驅(qū)動(dòng)器端口,。
• A housing-type valve can be installed close to the actuator or even directly into the actuator itself.阿住房型閥可安裝于近執(zhí)行機(jī)構(gòu),，甚至直接到驅(qū)動(dòng)器本身。
