Structural characteristics of hydraulic shut-off valve:
1. Flexible and reliable pneumatic to manual conversion mechanism. The pneumatic/manual switching mechanism installed on the upper part of the cylinder head can easily rotate the operating handle at any position during the opening and closing process of the shut-off valve, directly switching from pneumatic to manual or from manual to pneumatic. The switching operating handle adopts a positioning pin self-locking design, and after positioning, it is reliable and stable.
Product Introduction
J741 hydraulic shut-off valve
Structural characteristics of hydraulic shut-off valve:
1. Flexible and reliable pneumatic to manual conversion mechanism. The pneumatic/manual switching mechanism installed on the upper part of the cylinder head can easily rotate the operating handle at any position during the opening and closing process of the shut-off valve, directly switching from pneumatic to manual or from manual to pneumatic. The switching operating handle adopts a positioning pin self-locking design, and after positioning, it is reliable and stable.
2. When faults occur in the electromagnetic valve and its control circuit or air supply system, it can quickly switch to manual operation without the need for other auxiliary tools, ensuring the normal operation of the circuit and avoiding accidents.
3. Before the completion of the self-control system in the new construction project, this series of globe valves can be reliably used as manual globe valves, with flexible and quick actions. When the handwheel of this valve is rotated clockwise, the valve disc descends and cuts off the channel, which is considered closed. When it is turned counterclockwise, it is considered open.
4. This valve can be divided into pneumatic double acting type, pneumatic normally open type, and pneumatic normally closed type.
5. The working medium should flow upwards from below the valve disc (opposite to pneumatic)
6. This valve can be equipped with an electric or pneumatic communicator to send valve switch status information. Therefore, using this valve can achieve remote control, centralized control, and automatic control.
7. The cylinder of this valve is made of seamless steel pipe, with the inner surface coated with corrosion-resistant hard chromium and polished. It has the advantages of low friction, low corrosion resistance, high hardness, and long service life.
8. The sealing ring in the cylinder is made of nitrile rubber. The O-ring seal has reliable sealing performance and is easy to replace during maintenance.
