Using pressure self-tightening seal structure, adjustable nut or adjusting bolt to tight seal ring, the medium pressure, the greater the sealing performance, the better. Medium from flowing downwards (back).

Seat embedded body, body, disc sealing surface using cobalt-based hard alloy plasma spray welding and into. Hardness, resistance to abrasion. Stem the anti-corrosion treatment, nitride anticorrosion sex is strong.

Electric device is mainly composed of motor, reducer, torque control, schedule control mechanism, the operating mechanism, hand electric switching mechanism and so on, the valve closing is controlled by a torque limit institutions, schedule control mechanism for protection, the valve open position is controlled by a stroke control mechanism, torque limit agencies for protection, valve in addition to the on-site operation, also can operate over a long distance.

Installation instructions:

Electric valve should be installed vertically, as far as possible stem up, electric device allowed to work environment - 20 ~ + 40 degrees Celsius temperature, relative humidity ≦ 80%, no corrosion, no explosive gas environment. Electric actuator used in pipeline temperature below 350 ℃, the Q/SY1002-65, used for pipeline temperature higher than 350 ℃, the GB492-24-4 sodium based lubricants.

When installation should pay special attention to each type of valve travel size, moment, avoid by all means is over travel, super torque operation.
