The Unique DV-ST UltraPure diaphragm valve is available for pneumatic or manual operation. For pneumatic operation, the valves are controlled by actuators that operate at product pressures of up to 10 bar, depending on the valve size, diaphragm material (EPDM, PTFE/EPDM and TFM/PTFE) and actuator selected. There is also a range of easy-to-mount indication and control units from which to choose.
For manual operation, the diaphragm valves are controlled by turning a handle attached to the stem. The handle features standard over-closure protection to help prolong diaphragm life. All steel parts are made of stainless steel or composite material, depending on the handle type. |
