Flow Controllers

Flow controllers automatically control the flow rate of a gas or liquid according to a predetermined flow rate. They are not affected by fluctuations in conditions or pressure.

Pre-Set Flow Controller | DS1541

Pre-Set Flow Controller - Overview

The Pre-Set flow control valves provide a constant flow rate independent of line pressure changes. It is suitable for pure liquid applications. Operation is by means of a rubber orifice that reduces in size as the pressure increases, thus balancing the flow. Installation is possible on any plane to fit existing pipework. Available either screwed or as a wafer to fit between flanges. All materials are WRC-approved for use in drinking water systems.

Pre-Set Flow Controller - Features
- Easy installation and operation
- Maintains controlled water supply irrespective of pressure fluctuation
- Reduces pressure surge and water wastage
- Eliminates costly water bills

Platon Automatic Flow Controller - Overview

These automatic flow control devices are suitable for liquids or gases. Once adjusted to the required value, flow is maintained accurately at that rate independent of pressure fluctuations in the supply or varying backpressures downstream of the meter. No electrical power or external flow measurement input is required as the control system uses the line pressure available. These are ideal for blending or dosing applications to maintain the required delivery of valuable gases or liquids, despite process line pressure changes.

Platon Automatic Flow Controller - Features
- Automatic
- No power required
- Adjustable over wide range
- High accuracy
- Fast response
- Gases or liquids
- Suitable for use on flammable liquids

FV Automatic Flow Controller - Overview

Accurate flow control is vital to a wide variety of processes, for example blending and dosing applications. This controller automatically regulates the flow of liquids or gases by using available line pressure. Once set to the required value, flow is maintained accurately independently of supply pressure fluctuations or varying back pressure downstream, subject to certain minimum overall head loss requirements. No electrical power or external flow measurement input is required. By keeping the required fluid delivery rate constant, one can ensure consistent product quality irrespective of process liquid head changes throughout a batch. These controllers are used in flow control systems such as aircraft fuel delivery systems, to prevent the hazard of excessive flows and protect metering systems from over-speeding. On natural gas or fuel oil delivery systems to multiple burners, the units can maintain optimum flow rate to each burner independently. Available in sizes from 15mm to 100mm. All units can be fitted with a flow scale plate calibrated for process conditions. Once set to a flow rate, the Flostat maintains that flow independent of line pressure fluctuations,
