Features

· It integrates the dynamic balance and regulation functions, and adjusts the valve opening according to the flow demand. Nomatter how the system differential pressure fuctuates, as long as it is within the working range of the valve, the valve core can
automatically adjust to keep the flow constant.
· Anovel and unique rigid structure is adopted to overcome the shortcomings of the old diaphragm valve. Itis durable and has
a large adjustment range
Control flow accuracy:+5%
·No on-site commissioning required, reduce labor cost
·Once the system changes, there is no need to re-balance the system

Adjustment and dynamic balance function

   The structure of PEF1010 is divided into two parts: flow regulation part and dynamic balance part

   The flow regulating function can realize the setting and adjustment of the flow, and the motorized regulating and switching
functions of the valve can be realized with the actuator

   Dynamic balance function can realize dynamic balance of flow. The pressure sensing plate senses the differential pressurebetween the valve inlet and the valve cartridge (P1-P2) and adjusts the flow area of the outlet of the valve cartridge to keep dif.ferential pressure (P1-P2) constant. Thus, the flow remains constant
