Severn Trent Services has launched the Capital Controls series WP70CV3 gas-feed system designed to control chemical feed in water or wastewater applications.

The space-saving design of the series WP70CV3 features an automatic valve, flowmeter and vacuum gauge.

The system operates under sonic conditions for all flow ranges, eliminating the need for differential pressure regulators.

The gas feeder’s integrated, space-saving design is also said to save material costs and customer time in wiring, system piping and routine maintenance.

The wall-mounted gas feeder incorporates the Capital Controls series 70CV3000 Chloromatic intelligent gas-flow control valve, which responds to multiple process signals from a water flow transmitter and/or chlorine residual analyser, eliminating the need for continuous operator monitoring.

In addition, the series WP70CV3 includes a gas-flow indicator and vacuum gauge mounted on a heavy-duty panel.

The series WP70CV3 can be provided with optional integrally mounted and wired high- and low-vacuum switches.

With minor materials changes in the valve head and flow indicator, the series WP70CV3 can be used to control the feed rate of chlorine, sulphur dioxide, ammonia or carbon dioxide gas.

It can accommodate 11 different flowmeter capacities ranging from 10-3,000PPD (200g/h to 60kg/h), providing versatility in meeting gas-flow requirements.
