Self Activated Differential Pressure Control Valve Self Activated Valve Product overview: The AONE-BEST PDV series of self-actuated differential pressure control valve are hydraulic balancing valves that can keep pressure differences among users constant automatically. Used in the household metering heating system and flow-variable air-conditioning system can be conducive to autonomic conditioning of all users and terminal devices in the controlled system. Self-actuated differential pressure control valve can be further divided into water supply type and water return type according to different positions of installation. Performance and characteristics Use the tight bivalve clack structure with smaller unbalanced force. Be used in the heating (air-conditioning) system to keep pressure differentials of the control system constant. Characteristics are as followed: 1. Keep pressure differentials of the controlled system constant. 2. Support internal automatic adjustment of the…
