The Sunwell GL32 is a high-flow brass latching (bi-stable) solenoid valve designed for automatic control of air, water, light oils and compatible gases. Its servo-assisted diaphragm design delivers excellent flow performance whilst requiring only a short electrical pulse to change state, making it ideal for energy-efficient fluid control systems.
Once energised with a momentary DC pulse, the valve remains in its selected position without continuous electrical power. A reverse polarity pulse returns the valve to its original position, making the GL32 particularly suitable for battery-powered equipment, remote installations and applications where minimising power consumption is essential.
Manufactured from a forged brass body with stainless steel internal components, the GL32 combines robust industrial construction with reliable pilot-operated performance. Optional EPDM or FKM seals provide compatibility with a wide range of industrial media.
