Manufactured entirely from thermoplastic material for corrosion-free, safe operation.
Excellent resistance to environmental conditions, as well as chemical and mechanical effects.
Ideal for industrial applications, water treatment systems, and swimming pools.
Special double-union design for easy installation and dismantling.
Threaded locking ring allows removal of the nut under pressure when the valve is closed. Ensures absolute leak-tightness.
