Adopting a double acting cylinder, the valve is remotely controlled using either upper chamber intake or lower chamber intake, making it easy and flexible to operate. Cylinder media: compressed air, nitrogen. Simple structure, easy manufacturing and maintenance; Small work schedule and short opening and closing time; The sealing surface between the closing body (valve disc) and the valve seat adopts conical sealing, which has low closing force, erosion resistance, and reliable sealing. The valve seat can be a replaceable valve seat, which can be freely combined with the sealing surface material of the closing element to meet the working conditions and extend the service life.

Working principle

Most valves that use compressed air as a power source are remotely controlled, with action commands manually or automatically triggered by the main control room to activate the intake and exhaust solenoid valves and supply and exhaust compressed air to the actuator. Compressed air acts on the piston or diaphragm, overcoming the frictional force of valve action and the spring force on the valve stem, thereby pressing down (for valve loss opening) or lifting (for valve loss closing) the valve stem, driving the valve core to move up and down, and opening or closing the valve.

Product Features

1. The double acting cylinder is easy and flexible to operate.

2. The sealing surface adopts conical sealing, with low closing force, erosion resistance, and reliable sealing.

3. The valve stem has undergone quenching and surface nitriding treatment, providing excellent corrosion resistance and abrasion resistance.

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 suitable for various pressure, temperature, and medium working conditions& nbsp;
