Automatic Pilot Operated PRV

Pressure Reducing Valve

Pilot-Operated-Pressure-Reducing-Valve

Description

4Matic Pilot Operated Pressure Reducing Valve is designed for applications where the reduction of high inlet pressures to a safe and stable outlet pressure is required. The pilot assembly reacts to changes in downstream pressure allowing the main valve to modulate between the closed and open position ensuring a constant downstream set pressure. Once the downstream pressure reaches the pilot setting, the main valve will seal shut preventing damage downstream. Pressure regulation is not dependent upon flow rate, resulting in minimal pressure loss through the valve.

Pressure Relief / Sustaining Valve

Pressure-Relief---Sustaining-Valve

Description

4Matic Pressure Relief / Sustaining Valve is a pilot operated valve, designed specifically to relieve excess pressure. Pressure Relief Valve is designed to maintain constant upstream pressure within close limits. In operation, the valve is actuated by line pressure through a pilot control system, opening fast to maintain steady line pressure but closing gradually to prevent surges. The pressure-sustaining valves keeps constant pressure in a line regardless of variations in inlet pressure. If the inlet pressure increases for any reason the sustaining valve keeps the outlet pressure constant and reduces hammering in the pipe line.

Altitude Control Valve

Altitude-Control-Valve

Description

The Altitude Control Valve by 4Matic Valves is a pilot-operated hydraulic control valve designed for precise and automatic water level regulation in overhead tanks and reservoirs.

The valve automatically closes when the tank reaches the preset level and reopens when the water level drops, ensuring consistent supply while preventing overflow and water wastage.

Manufactured with high-quality materials and a robust diaphragm-actuated design, the valve provides excellent durability, corrosion resistance, and reliable long-term performance. It is widely used in municipal water supply systems, industrial facilities, irrigation networks, and water management infrastructure for efficient and dependable water level control.

Float Valve

Float-Valve

Description

4Matic Float Valve is a Globe Design Pilot Operated Diaphragm Actuated Valve. It is installed at the inlet of the tank/reservoir, it allows to keep a constant/ set level of water. As the Float is linked to the Pilot it ensures to stop the flow of water at predetermined Level while realizes water supplement when the float lowers. This Valve helps to keep a Constant level of water in the Tank. This valve can work in a remote location, perfect for all those applications where the water tank is not easily accessible.

Level Control Valve

Level-Control-Valve

Description

4Matic Level Control Valve is a Globe Design Pilot Operated Diaphragm Actuated Valve. It is installed at the inlet of tank/reservoir, unlike a float valve it allows you to adjust the level of water as desired. As the Level Float is linked to the Pilot it ensures to Stop the Water Filling at predetermined Level while realizes water supplement when the float lowers to the desired level. This Valve helps to keep the optimal Water level in the Tank. The valve can work in remote location and does not require any Power Supply, so it is perfect for all those applications where the water tank is not easily accessible.

Smart Control Valve

(Dual Solenoid Scada Compatible Flow Control Valve)

Smart-Control-Valve

Description

4Matic Dual Solenoid Scada Compatible Flow Control Valve is used for applications where reduction in flow is required. In this valve two solenoid valves are used as pilot valves to control Flow and Pressure of the main valve.

When pulse is given to the solenoid valve at the inlet, the main valve will close because the upper chamber will get filled with water and will close the diaphragm. The tension on the spring will close the main valve.

When pulse given to the solenoid valve at the outlet, the main valve will gradually open, as the pressure in the upper chamber of main valve is released and the media can flow out from the main valve.

Electric Actuator Operated Pressure Reducing Valve

Electric-Actuator-Operated-Pressure-Reducing-Valve

Description

4Matic Electric Actuator Operated Pressure Reducing Valve is a globe-design, pilot-operated, diaphragm-actuated valve designed for automatic pressure regulation. It is equipped with an electric actuator-operated pressure reducing system that allows users to adjust the pressure according to their requirements through a PLC panel. In this valve, the electric actuator is integrated with the pressure reducing pilot. 

The electric actuator controls the pilot valve, which regulates the operation of the main valve to maintain the desired pipeline pressure. When the pressure setting is adjusted through the PLC panel, the electric actuator operates the pressure reducing pilot accordingly. 

This allows the main valve to regulate the downstream pressure and helps maintain the required pressure level in the pipeline. The 4Matic Electric Actuator Operated Pressure Reducing Valve is suitable for applications requiring automatic pressure regulation, PLC-based control, and remote pressure adjustment, reducing the need for frequent manual intervention.
