Description

3 Inch DN80 Bronze Flanged Solenoid Valve – NC & NO – Sunwell LD80B & RL80B

The Sunwell LD80B and RL80B are heavy-duty 3 inch (DN80) bronze flanged solenoid valves designed for reliable automatic control of water, air, diesel fuel and other compatible industrial fluids. Available in either normally closed (LD) or normally open (RL) operation, both valves utilise a pressure-assisted diaphragm design for dependable high-flow performance.

Manufactured from a one-piece bronze body with stainless steel internal components, these valves are suitable for demanding industrial applications where durability, long service life and reliable operation are essential.

Supplied with NBR seals as standard, the valves are also available with optional FKM seals for higher temperature applications. An optional ATEX certified coil is available for hazardous area installations.
