FAQs

The EFVFGJS is used for automatic water level control in tanks, ponds and reservoirs, regulating inlet flow as the water level changes.
As the water level rises, the float moves the control arm and gradually closes the valve. When the level drops, the valve opens again to allow water inlet.
The balanced piston sealing system compensates pressure effects on the obturator, improving shut-off reliability and stable operation.
No. It is a fully mechanical self-operated valve and does not require electrical power, pneumatic supply or external control systems.

ABOUT EFVFGJS

The EFVFGJS Balanced Float Valve is designed for automatic water level control in tanks, reservoirs and ponds, regulating the inlet flow as the water level rises or falls. Its balanced piston sealing system compensates pressure effects on the obturator, ensuring effective closure and stable operation under variable inlet pressure conditions.

Manufactured with a GGG40 nodular iron body, AISI 304 stainless steel arms and shaft, NBR sealing components and a durable PVC float, the EFVFGJS offers long service life, low head loss and reliable operation in water storage and distribution applications.

Available from DN50 to DN250, with DIN PN10/16 flanged connections and 200 μm epoxy coating RAL 5017, the EFVFGJS is a practical solution for water networks, reservoirs, irrigation systems and industrial tanks requiring mechanical, maintenance-free level control.

No. It is a fully mechanical self-operated valve and does not require electrical power, pneumatic supply or external control systems.
The EFVFGJS is available from DN50 to DN250.
The valve is designed for working pressures up to 16 bar.
The EFVFGJS is supplied with DIN PN10 / PN16 flanged connections.
The valve includes a GGG40 nodular iron body, AISI 304 stainless steel arms and shaft, NBR sealing components and a PVC float.
The valve is supplied with 200 micrometer epoxy coating in RAL 5017.
It is designed as a maintenance-free solution, although periodic visual inspection is recommended in critical installations.
For transport and installation convenience, the valve is normally supplied in three parts: valve body, float arm and float assembly.
It should be installed in the upper part of the tank, with proper fixing and sufficient free movement for the float arm.
Yes. If the water may contain sand, rocks or debris, a filter is recommended to protect the valve and reduce maintenance risk.
It may be suitable depending on project requirements and applicable local approvals. Potable water compatibility should be confirmed case by case.
Selection depends on flow rate, inlet pressure, tank dimensions, operating level and installation arrangement.
