Control Valve Characteristics

The setup is designed to understand the control valve operation and its flow characteristics. It consists of pneumatic control valves of linear, equal% (& quick opening for product 318B) type, stainless steel water tank with pump for continuous water circulation and rotameter for flow measurement. An arrangement is made to measure pressure at the valve inlet in terms of mm of water air regulator and pressure gauge is provided for the control valve actuation. In case of additional optional requirement a valve positioner is fitted on linear valve. The set up is stand-alone type.

Features:
