Heavy Duty Mechanical Float Valves

Model / Series: E403

Built for demanding environments

Envotec Equilibrium Float Valves E403 are mechanical float valves designed to automatically control water level in tanks and reservoirs. The valve modulates opening and closing in response to water level fluctuations, ensuring reliable level control across residential, commercial, industrial, and irrigation applications.

The E403 Series Equilibrium Float Valves feature an all-bronze body construction with high-tensile manganese bronze arms and a brass connecting stem. Designed for durability and smooth operation, the valve incorporates a single plunger, non-jamming action with replaceable seals. An adjustable thumb screw allows precise setting of the required water level. Float options include UV-resistant PVC (standard) or copper (optional).
