Flange type electric hard seal globe valve

1 j941h—16c dn150Flange type electric hard seal globe valvesummary:

It consists of an electric actuator and a shut-off valve,Electric flange globe valveThe opening and closing component is a plug shaped valve disc, with a flat or conical sealing surface, and the valve disc moves in a straight line along the centerline of the fluid. The movement form of the valve stem includes a lifting rod type (the valve stem is lifted and lowered without the handwheel lifting), as well as a lifting rotating rod type (the handwheel rotates and lifts together with the valve stem, and the nut is set on the valve body).Electric flange globe valveOnly applicable to fully open and fully closed, adjustment and throttling are not allowed.

II j941h—16c dn150Flange type electric hard seal globe valveFeatures:

① The sealing surface of the valve disc and seat is made of hard welding, which is wear-resistant, high-temperature resistant, corrosion-resistant, scratch resistant, and has a long service life.

② The valve stem material is nitriding steel, and the surface of the valve stem after nitriding has high hardness, wear resistance, abrasion resistance, and corrosion resistance.

③ Due to temperature, pressure, and other factors, valve bodies and covers with diameters below DN50 are made of forged parts, while valve bodies and covers with diameters above DN65 are made of cast steel.

④ The valve body material variety is complete, and the packing and gasket can be reasonably selected according to actual working conditions or user requirements, which can be applicable to various pressure, temperature, and medium working conditions.

⑤ When installing the valve, pay attention to the flow direction of the medium and install it strictly in the direction indicated by the valve flow arrow.

⑥ Electric globe valves should be installed vertically as much as possible, with the valve stem facing upwards.

IIICharacteristics of the actuator:

1. Power supply: The motor is three-phase AC, 380V (special order 660V or 220V), 50Hz (special order 60Hz); The control line is 220V, 50Hz (special order 60Hz); Remote control is 24VDC.
2. Work environment:
(1) Environmental temperature: -20 to+60 ℃ (special orders -60 to+80 ℃).
(21) Relative humidity: ≤ 90% (at 25 ℃).
(3) Ordinary and outdoor types are used in places without flammable/explosive and non corrosive media; There are two types of explosion-proof products, dI and dIIBT4. dI is suitable for non mining working faces in coal mines; DIIBT4 is used in factories and is suitable for explosive gas mixtures in IIA and IIB level T1 to T4 environments.
