PNEU-HYDRO阀PH183834-P介绍
这种三通、两位置、常闭阀占据了传统隔膜接口阀约三分之一的空间，能够允许来自内部气动先导的低压信号控制高压液压动力系统。先导部分可承受高达1000 psi的压力，而液压部分可承受高达10000 psi的压力。
在独特的阀芯设计中，通常的先导隔膜被活塞取代。使用不锈钢活塞和兼容密封件能够消除因隔膜泄漏和隔膜与工艺流体不兼容而导致的故障。
液压动力压力与先导控制压力之间的高比例确保了在各种条件下的安全操作和可靠控制。50 psi的先导压力可以控制5000 psi的液压动力，而80 psi的先导压力可以控制10000 psi的液压动力。
柔性密封设计确保液压动力部分零泄漏。金属对金属的密封确保在紧急情况下不会泄漏。
故障安全关闭得到了保证，因为内部弹簧和作用于差压阀芯区域的液压压力都提供了足够的力来实现关闭。通常情况下，两者都 acting 来关闭阀门。阀芯延伸部分提供了操作状态的正指示，能够移动以显示阀门位置。
该阀具有优良的流量能力，Cv值为0.5，相当于直径为0.224英寸的孔口。
虽然有些细微差别，但此版本的尺寸和操作参数相同。手动超越版本在活塞外壳顶部中心位置配有一个旋转手柄。
Occupying about a third of the space required by conventional diaphragm interface valves, this three-way, two position, normally closed valve permits a low pressure signal from an internal pneumatic pilot to control a high pressure hydraulic power system. The pilot section handles pressures of up to 1,000 psi and the hydraulic section accommodates pressures of up to 10,000 psi.
In the unique spool valve design, the usual pilot diaphragm is replaced by a piston. The use of a stainless steel Piston and compatible seal eliminates failures due to diaphragm leakage and incompatibility of diaphragm with process fluid.
A high ratio of hydraulic power pressure to pilot Control pressure insures safe operation and positive control under
all conditions. A pilot pressure of 50 psi controls 5,000 psi hydraulic power, and 80 psi pilot pressure controls 10,000 psi hydraulic power pressure.
A soft seal design insures zero leakage in the hydraulic power section. Metal-to-metal seating insures against leakage in emergency situations.
Failsafe closure is insured, as both the internal spring and hydraulic pressure acting on the differential spool area provide suffi cient force to effect closure should one or the other fail. Normally both act to close the valve. A positive indicator of operation is provided in the spool extension, which shifts to show position.
Excellent fl ow capacity is provided with a value of Cv = 0.5 or the equivalent of an orifi ce of 0.224 inch diameter.
With minor differences the dimensions and operating parameters are the same for this version. The Manual override version has a turning handle located at the top center of the piston housing.
