Product Description

J941H mine explosion-proof electric stop valve is composed of explosion-proof electric actuator and stop valve. The opening and closing part is a plug shaped valve disc, the sealing surface is flat or conical, and the valve disc moves in a straight line along the center line of the fluid. The movement form of the valve stem, there are lifting rod type (the valve stem lifting, the handwheel does not lift), there are also lifting rotary rod type (the handwheel and the valve stem rotating lifting together, the nut is set on the valve body). Can be applied to a variety of pressure, temperature and media conditions. Valve in the pipeline is mainly used to cut off, distribute and change the flow direction of the medium, generally do not adjust the use, because the adjustment of the unbalanced force is too large, the erosion of the valve core is more serious.

Product Features

1. Simple structure, convenient manufacture and maintenance.
2, the valve stem after tempering and surface nitriding treatment, has good corrosion resistance and abrasion resistance.
3, suitable for use as an automatic cutting medium.
4, good sealing, small friction between the sealing surface, long life.
5, the valve stem opening or closing stroke is relatively short, and has a very reliable cutting action.
6. The seat and disc are relatively easy to repair or replace the sealing element without removing the whole valve from the line.
7, the reverse seal is made of threaded sealing seat or body surfacing welding austenitic stainless steel, reliable sealing, replacement packing can be carried out without stopping, convenient and fast, does not affect the operation of the system.
8, the electric actuator is easy to operate.
