The Application of differential pressure controller

Chinabase Machinery is a group of manufacturing facilities, offering one-stop solution for mechanical power transmission products in China. 

We can supply a full-range of power transmission products, such as chains, sprockets and plate wheels, pulleys, gearboxes, motors, couplings, gears and racks. Our product range also covers locking assemblies (clamping elements/locking device), taper bushes, Timing Belt Pulleys，QD bushes, bolt-on hubs, torque limiters, shaft collars, motor bases and motor slides, chain detachers, chain guides, universal joint, rod ends and yokes. 

Chinabase is able to offer custom, cost-optimized solutions in accordance with customer drawings - such as ready-to-install machine parts and profiles - in addition to our standard products. 

Differential pressure controller combined two has high sensitivitypressure element, two once changed, that is caused by theswitching mechanism of action to control devices such as motor driven valve. Switch mechanism to provide SPDT of non rapidaction (floating) action, therefore shared the movable contact,contact with one of the two fixed contact, or stay in between the two(no contact).

Application

P74JA differential pressure controller is usually applied to the water system, used to control water supply pipe and the water return pipeof the pressure difference between. Controller SPDT floating actionmake contact, make the motor drive control valve. A typical application is, the by-pass valve installed in the pump system in the vicinity of the. When the system pressure increases more than the controller set value, the valve is then opened, more water to flow through the bypass valve, so that the system pressure decrease.Differential pressure reducing valve began to increase small andsystem pressure difference.

Agricultural Chain

P74JA is also suitable for other gas or liquid pressure difference.

All P74 series controller is designed only as control use.

If the operation is out of control, cause personal injury or property loss may, the installer is responsible for additional facilities (safety,limit control), protected, or adding system (alarm, monitoring system), sound an alarm in the control.
