HRVO電動(dòng)O形切斷球閥適用于兩位切斷、調(diào)節(jié)的場合。閥與執(zhí)行機(jī)構(gòu)的連接采用直連方式，電動(dòng)執(zhí)行機(jī)構(gòu)內(nèi)置伺服系統(tǒng)，無須另配伺服放大器，輸入4-20mA信號(hào)及220VAC電源即可控制運(yùn)轉(zhuǎn)。具有連線簡單，結(jié)構(gòu)緊湊、尺寸小、重量輕、阻力小、動(dòng)作穩(wěn)定可靠等優(yōu)點(diǎn)。執(zhí)行機(jī)構(gòu)可根據(jù)用戶要求另配置UNIC、PSQ、HQ、DHL等型號(hào)電子式電動(dòng)執(zhí)行機(jī)構(gòu)或GTX、AL等氣活塞式執(zhí)行機(jī)構(gòu)。

HRVO electric O-off valve for two off, adjust the occasion. Valve and actuator connections using direct connection, built-electric actuator servo system without reprovisioning servo amplifier, the input 4-20mA signal and 220VAC power to control operation. A connection is simple, compact structure, small size, light weight, resistance, stable and reliable. Actuator can be configured according to user requirements other UNIC, PSQ, HQ, DHL and other types of electronic electric actuator or GTX, AL and other gas-piston actuators.
