ZDR Direct operated pressure reducing valveDealer in Chennai. type ZDR is a direct worked pressure lessening valve in sandwich plate plan with pressure limit of the auxiliary circuit. It is utilized to diminish the framework pressure. The tension decreasing valve fundamentally involves lodging, control spool, pressure spring, change type and a discretionary actually take a look at valve. The optional tension is set by means of the change type.
Variant “A”
The valve is open in introductory position. Pressure driven liquid can move from channel A to channel A without limitations. The strain in channel An is at the same time applied through the control line at the cylinder region inverse the pressure spring. Assuming the tension in channel A surpasses the worth set at the pressure spring, the control spool is pushed against the pressure spring to control position and keeps the set strain in channel An at a steady level. Control sign and pilot oil are provided inside by means of the control line from channel A. Assuming the strain in channel An increments further because of an outer power impact at the actuator, it pushes the control spool considerably further against the pressure spring.
Along these lines, channel An is associated with the tank through the control edge at the control spool and the lodging. Such a lot of water driven liquid is released into the tank that the tension doesn’t build any further. The spillage oil channel from the spring chamber is generally affected remotely through the drag and channel T (Y). A tension check association takes into consideration the control of the optional strain at the valve. A check valve can be utilized with the expectation of complimentary stream back from channel A to A with adaptation “A”. Forms “P” and “B” With adaptation “P”, the strain decrease is affected in channel P.
Control sign and pilot oil are provided inside from channel P. With rendition “B”, the strain is decreased in channel P; however the pilot oil is removed from channel B. ZDR Direct operated pressure reducing valveDealer in Chennai.
