进口小口径单座调节阀（德国OLES阀门品牌）

进口小口径单座调节阀(德国奥莱斯OLES阀门品牌)

【进口小口径单座调节阀】详细说明：

气动调节阀单座调节阀阀体，适用于对泄露量要求严格、阀前后压差低及有一定粘度和含少量纤维介质的场合。气动流量调节阀,按照开关方式的不同可分为常开气关式和常闭气开式两种。气关式阀由正作用执行机构和调节阀阀体组成。当输入信号压力由下限值改变为上限值时，阀从全开到全关。气开式阀由反作用执行机构和调节阀阀体组成，当输入信号压力由下限值改变为上限值时，阀从全关到全开。精小型气动调节阀是以压缩空气为动力源，以气动薄膜式或者气动活塞式为执行机构，选配电气阀门定位器、电气转换器、电磁阀、保位阀等附件来实现开关量或比例式调节，接收工业自动化控制系统的控制信号来完成管道介质的：流量、压力、温度等各种工艺参数的控制。

Pneumatic control valve single seat control valve body, suitable for strict leakage requirements, low pressure difference before and after the valve, with a certain viscosity and a small amount of fiber medium occasions. Pneumatic flow control valves can be divided into two types according to the different switching modes: normal opening and normal closing. The air-closed valve is composed of a positive actuator and a regulating valve body. When the input signal pressure changes from the lower limit to the upper limit, the valve is fully open to fully close. The air-opened valve is composed of reaction actuator and control valve body. When the input signal pressure changes from lower limit to upper limit, the valve closes completely to open completely. Fine and small pneumatic control valves use compressed air as power source, pneumatic thin film or pneumatic piston as actuator, select and distribute pneumatic valve positioner, electrical converter, solenoid valve, holding valve and other accessories to realize switching or proportional regulation, and receive control signals of industrial automation control system to complete pipeline introduction. Quality: Flow, pressure, temperature and other process parameters control.
