气动角座阀、常规、执行器 大小头选型

常闭型执行器低控制压力为0.4Mpa，在介质压力高于控制压力，控制压力且只有0.4MPa的情况下阀门有打不开的现象，这种情况选用大头，加大执行器到80，以及100，常开型在防水锤安装下，介质压力高于执行器控制压力，需要采用大头，加大执行器。具体非常规安装联系我们根据实际管道介质压力、温度以及压力控制选型。

根据用户要求可配备附件：电磁阀，限位开关，减压阀过滤器，接近开关，信号反馈，定位器等，所有规格，均可根据用户使用定制，必要时可派专业人士，现场设计以及安装。

角座阀保持流速能够节省空间，采用弹簧安全保护的单作用执行器机构来操作的导向角座阀，可广泛应用于短时间频繁启动，具有反应灵敏，动作准确的特点，配合电磁阀使用，用气动控制可准确控制气体，液体流量，可实现准确控温，滴加液体等要求，温热灭菌应用角座阀控制汽量准确控温。

The minimum control pressure of the normaly closed actuator is 0.4Mpa. When the medium pressure is higher than the control pressure and the control pressure is only 0.4 Mpa, the valve will not open. In this case, use a large head and increase the actuator to 80. And 100, nomallyopen type, under the installation of the waterproof hammer, the medium pressure is higher than the control pressure of the actuator, you need to use a large head to increase the actuator. For specic unconventionalinstallation, contact us to select the model according to the actual pipeline medium pressure, temperature and pressure control.

According to user requirements can be equipped with accessories: solenoid valve, limit switch, pressure reducing valve filer, proximity switch, signal feedback, positioner, etc., al specifications can be customized according to user use, if necessary, can send professionals, site design and installation.

The angle seat valve maintains the flow rate and saves space. The pilot angle seat valve operated by a spring-actuated single-acting actuator mechanism can be widely used in short-time and frequent start-up. Pneumatic control can accurately control the fow of gas and iquid, and can achieve accurate temperature control, drop iquid addition and other requirements. Warm sterilization uses angle seat valve to control steam volume to accurately control temperature.
