Balancing Valves
Bronze fixed orifice double regulating valve
- The bronze commissioning range offers accuracy of +/-5% on all settings. The integral fixed oriface design offers greater accuracy, makes set-up easier and involves fewer connections reulting in lower installation costs.
- WRAS and Kitemark approved
- Suitable for working pressure up to PN25
- DN ½"-2"

Ductile Iron Variable Orifice Double Regulating Valve
- The double regulating feature allows the valve to be used for isolation and to be re-opened to its pre-set position to maintain required flow rate
- Flow accuracy measurement of +/-10% at fully open position
- PN16
- DN65-300
Ductile Iron Fixed Orifice Double Regulating Valve
- Single unit Y-Pattern globe valves incorporating an integral orifice plate to form a fixed orifice flow measurement unit with regulation and isolation capacity

Dynamic Flow (Autoflow) Balancing Valve (50-500mm)
- Generally used in a constant flow system
- The flow rate is factory preset, multiple ∆P ranges available for each size
- Precision calibrated valve plug keeps the flow deviation no greater than ±5%
- No on-site commissioning, saving labor costs
- Dynamic Balance: When the system differential pressure generates fluctuation, the spool automatically adjusts the variable runner opening and can achieve the constant flow in the controlled area
- PN25
