ZAZTElectric diaphragm regulating valve
1、 Product Details
Product Model:ZAZT
Product Name: Sanjiu Electric Diaphragm Regulating Valve
ZAZTElectric diaphragm regulating valveIt can also be used as a shut-off valve within the allowable pressure difference range. The flow characteristics are approximately fast opening characteristics. The valve body flow channel of the automatic diaphragm valve is smooth, and the throttling element is an elastic diaphragm. The rated flow coefficient is larger than that of a general regulating valve. The elastic diaphragm also plays a sealing role and has no leakage. Therefore, the valve cover of the diaphragm valve has no packing box, a simple structure, easy maintenance, and the medium does not come into contact with the outside world. Therefore, it can also be used for regulating toxic and polluted media.
The valve body with corrosion-resistant lining and the diaphragm valve with corrosion-resistant diaphragm can avoid corrosion of the metal valve body of the lining matrix. Suitable for regulating strong acids, strong bases, and highly corrosive media.

7、 Precautions for use
Installation of ZKZT electric diaphragm regulating valve
·It should be installed vertically on pipelines, and those with large volume and weight, as well as those used in vibration situations, should be supported and clamped.
·Generally, a bypass pipeline should be installed so that it can be switched to bypass operation in case of diaphragm failure or maintenance, allowing the production process to proceed normally. In non critical situations, the bypass pipeline can be omitted after installing the handwheel mechanism for manual operation, and the valve opening can be limited. When the handwheel mechanism stops using, it should be restored to its original neutral position to facilitate the normal operation of the self-control system.
·When cleaning the pipeline, the adjustment should be at the maximum opening to remove dirt from the pipeline.
·If the valve body is lined with an anti-corrosion layer, a corrosion-resistant soft pad should be used when installed on the pipeline, and care should be taken not to damage the sealing surface of the valve body flange.
·The diaphragm and lining should be regularly inspected to prevent damage to other parts and accidents caused by corrosion and rupture.
