TOP GUIDE SLEEVE CONTROL VALVE
The valve core uses the pressure balance structure, with small opening and closing force. The working condition of high pressure difference can be controlled by the small actuator thrust. It is widely used in the fluid control of medium low temperature and medium low pressure pipelines which require good dynamic stability. Good sealing performance and large allowable pressure difference. Copper sleeve guide, large guide area, good stability, compact structure, can quickly replace valve internals online, high maintenance efficiency, save manpower and time. The balance valve core structure ensures the minimum actuator thrust.
