Description

1/2 Inch Nylon Solenoid Valve – Zero Pressure 2/2 Way NC – Sunwell PK15

The Sunwell PK15 is a high-performance 1/2 inch nylon solenoid valve designed for reliable operation with zero pressure differential. Its assisted-lift diaphragm design allows the valve to open from vacuum or zero pressure, making it ideal for low-pressure water systems, demineralised water, reverse osmosis (RO) equipment, vacuum applications and light chemical processes.

The corrosion-resistant nylon body combined with stainless steel internals provides excellent durability while keeping weight to a minimum. EPDM seals are supplied as standard, with optional NBR or FKM seals available for wider media compatibility.

Available with AC or DC coils, the PK15 features continuous 100% duty operation, DIN 43650A electrical connection and an optional ATEX certified coil for hazardous area installations.
