常閉型執(zhí)行器低控制壓力為0.4Mpa，在介質(zhì)壓力高于控制壓力，控制壓力且只有0.4MPa的情況下閥門有打不開的現(xiàn)象，這種情況選用大頭，加大執(zhí)行器到80，以及100，常開型在防水錘安裝下，介質(zhì)壓力高于執(zhí)行器控制壓力，需要采用大頭，加大執(zhí)行器。具體非常規(guī)安裝聯(lián)系我們根據(jù)實(shí)際管道介質(zhì)壓力、溫度以及壓力控制選型。

根據(jù)用戶要求可配備附件：電磁閥，限位開關(guān)，減壓閥過濾器，接近開關(guān)，信號反饋，定位器等，所有規(guī)格，均可根據(jù)用戶使用定制，必要時可派專業(yè)人士，現(xiàn)場設(shè)計以及安裝。

角座閥保持流速能夠節(jié)省空間，采用彈簧安全保護(hù)的單作用執(zhí)行器機(jī)構(gòu)來操作的導(dǎo)向角座閥，可廣泛應(yīng)用于短時間頻繁啟動，具有反應(yīng)靈敏，動作準(zhǔn)確的特點(diǎn)，配合電磁閥使用，用氣動控制可準(zhǔn)確控制氣體，液體流量，可實(shí)現(xiàn)準(zhǔn)確控溫，滴加液體等要求，溫?zé)釡缇鷳?yīng)用角座閥控制汽量準(zhǔn)確控溫。

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.
