Product Profile of Hydraulically Actuated Diaphragm Valves

Positive metering pumps [i] pvt ltd has been involved in the activity of manufacturing a range of dosing pumps and dosing systems for various applications. As part of that, hydraulically actuated diaphragm valves are offered. In these valves diaphragm is always balanced between the pressure applied by the hydraulic oil and the liquid to be dosed. Some key features of these hydraulically actuated diaphragm valves are as follows:

• Metering accuracy is almost independent of back pressure

• Flow rate is linear to stroke length variation

• Automatic air bleeding from the hydraulic oil

• Arrangement of in-built pressure relief valve to protect the pump from pressure exceeding the rated pressure

• Rupture indication arrangement as an additional facility

• The rupture of any one of the diaphragms can be sensed by pressure sensing device
