HYDROMINE™ LFC_3B Pressure Control Valve
OVERVIEW
A pressure control valve is designed to maintain a desired downstream pressure irrespective of the flow requirement. The HYDROMINE™ LFC_3B pressure control valve is fitted with a modulating intelligent electrical actuator. Any make of electrical actuator can be fitted to the pressure control valve. The HYDROMINE™ LFC_3B pressure control valve has been developed to present a robust, simple and cost-effective low pressure (up to 2.5 MPa / 363 psi) solution to fluid handling issues in any industrial sector.
SIMPLICITY
The HYDROMINE™ LFC_3B pressure control valve is designed to offer increased efficiency and accuracy as well as improve on ease of maintenance and in effect only has one moving part called the plug. The plug is a piston that is engineered to be balanced. The balanced plug enables easy opening and closing at any pressure and differential condition. The differential pressures do not affect the operating torque which results in a relatively flat torque curve allowing for the fitment of smaller actuators.
FEATURES
- Reduced cavitation
- Low noise levels
- Low vibration
- One moving part
- Long lasting
MATERIALS OF CONSTRUCTION & DIMENSIONS
All face to face dimensions are in accordance with ANSI B16.10 Class 150.
LOW MAINTENANCE REQUIREMENT
All the moving parts of HYDROMINE™ LFC_3B pressure control valve are manufactured from stainless steel which increases reliability and durability. The HYDROMINE™ LFC_3B requires minimal maintenance, the majority of which, can be conducted with the valve remaining in situ.

Please consult with HYDROMINE™ Projects International for clarification of correct sizing for your requirements.
PLUG ASSEMBLY, V-PORT AND DEALING WITH CAVITATION
As displayed, the HYDROMINE™ LFC_3B pressure regulating valve plug assembly and movements.
Closed Position: Shows the plug assembly on the body seat in a fully closed valve position.
5% Open Position: Shows the plug assemble in a 5% open position. It can clearly be seen that only the top of the V-Port opens and creates a flow path. This reduces cavitation and helps with fine control at low flow conditions.
12% Open Position: Shows the plug assembly in the 12% open position. Now it can be observed how the V-Port moved away from the seat and the openings are increasing proportionally. At this point the top of the V-Ports is now being exposed to the flow path.
30% Open Position: Shows the plug assembly in the 30% opened position. Now it can clearly be seen that the full V-Port is creating a larger orifice in the flow path. Up to this point, cavitation needs to be dealt with to increase the life expectancy of the valve. The V-port trim ensures that the seating elements are further apart from each other during low flow allowing the cavitation to take place on noncritical components of the valve.
40% Open Position: Shows the plug assembly in the 40% open position. Now it can clearly be seen that the V-Port is completely away from the seat and the flow path is now relatively large. At this point the flow is approaching its medium demand flow rate and the V-Port has little to no function.
ROBUST, RELIABLE AND EFFICIENT
Due to the minimal number of moving parts to affect the fluid control, the number of potential failures are minimized.
