4MPFV Series
Equilibrium Level Control Float Valve
Size Range : 3″ To 12″
Description
The 4MPFV Series Equilibrium Level Control Float Valve by 4Matic is a high-performance hydraulic control valve designed to automatically maintain a constant water level in storage tanks, reservoirs, and water distribution systems.
This valve operates using a float-controlled pilot mechanism that senses the water level in the tank. When the water level drops, the valve opens automatically to allow water to enter the tank. Once the desired level is reached, the valve closes smoothly, preventing overflow and ensuring efficient water management.
The equilibrium design ensures stable operation, accurate level control, and reduced hydraulic shock, making it ideal for municipal, industrial, and irrigation water systems.
Features :
- Automatic Water Level Control : Maintains constant water level in tanks and reservoirs
- Equilibrium Operation : Smooth opening and closing with stable flow control
- Float Pilot Mechanism : Accurate level sensing for reliable valve operation
- Overflow Prevention : Automatically stops water supply when tank is full
- Durable Construction : Designed for long service life in demanding environments
- Low Maintenance Design : Simple pilot system ensures easy maintenance
- Corrosion Resistant Epoxy Coating : Suitable for water supply applications.
