Features
- The P24C is a pressure reducing and flow compensator pilot that adjusts the downstream pressure set point in proportion to measured flow
- During high demand the set point rises to maintain adequate supply pressure; during low demand it falls to reduce background leakage
- Unlike time-based pilots, the P24C responds to actual network conditions in real time, giving the optimum balance between pressure and leakage at all times
- Top and seat ring guided stem and diaphragm assembly for long life and reliability
- All iron components are fusion epoxy bonded for corrosion resistance
- Easy maintenance without removal from the main line
- Nylon reinforced diaphragm for long-term service
- Drip-tight shut-off
- Globe design for superior control characteristics
- Ductile iron bodies for higher strength and durability
- Corrosion-resistant stainless steel seat and disc retainer ring
- Various pilots and accessories available for configuration into many different applications
- Special V-Port and double chamber are options, consult factory
- Meets BS EN 1074-5, ISO 5208, BS EN 12266-1 and BS EN 558-1
Description
The P24C is a pressure reducing and flow compensator pilot that adjusts the downstream pressure set point in proportion to measured flow. During high demand the set point rises to maintain adequate supply pressure; during low demand it falls to reduce background leakage. Unlike time-based pilots, the P24C responds to actual network conditions in real time, giving the optimum balance between pressure and leakage at all times.
Selection notes
This control valve is supplied for flanged installation.
Sizes run DN50 to DN1000, in PN10, PN16, PN25, ANSI 125, ANSI 150.
The body is EN-GJS-500-7.
Seat and trim options are AISI 304 and 316. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.
Stated service media include water.
It is catalogued for Water & Wastewater.
Working temperature is -10°C to 80°C.
Built to BS EN 1074-5, BS EN 558-1, ISO 5208 and BS EN 12266-1.
