2way Manifold Valve
2-Way valve manifolds are designed for connecting system impulse line & transmitters. These Manifolds consist of two valve configurations which allow for easy isolation, calibration, block and bleed for gauges, pressure switches and static pressure transmitting instruments. These manifolds are rugged in construction to withstand high pressures and temperatures. These Manifold Valves combine the functions of a tee, calibration valve, isolation valve and all tubing and fittings into a single compact unit thus reducing the number of fittings and space required for installation.
3Way Manifold Valve
3-Way valve manifold is a device that is used to ensure that the capsule will not be over-ranged. It also allows isolation of the transmitter from the process loop. It consists of two block valves – high pressure and low-pressure block valve – and an equalizing valve. Two block valves provide instrument isolation, and one equalize valve is positioned between the high and low transmitter process connections to provide equal pressures on both sides.
5Way Manifold Valve
5-Way valve manifold is used for differential pressure transmitter. The typical 5-way valve manifold consists of 2 block valves, 1 equalizer valve, and 2 vent or test valve. If we want to check the zero of the transmitters, we just need to close the block valve and open the equalizing valve. If we want to calibrate the transmitter for 3- or 5-point calibration, then after the pressure is equalized, we just need to connect the test valve to a pressure generator. This 5-way valve manifold is the most common valve manifold for differential pressure transmitter.
A manifold is a device that connects one or more block/isolate valves of a hydraulic system. Valves of a hydraulic system can include a ball, needle, bleed, and vent valves. In the case of a block and bleed manifold, the purpose is to ensure that the fluids from upstream do not meet the components from downstream. This is achieved through isolating the flow of the fluid in the system.
Manifolds are typically used with a particular number of valves based on the operation required. The most common are 2-valve, 3-valve, and 5-valve assemblies.
2-valve manifolds are usually used on gauge pressure transmitters where there is a need to isolate the transmitter and vent the pressure off.
3-valve manifolds are normally used on differential pressure transmitters where it is necessary to block each process connection or equalize two sensor diaphragms.
5-valve manifolds are also used on differential setups and provide the ability to block, equalize and vent two process connections.
Valve manifolds can be useful in many situations, from small mobile machines to heavy industrial plants. Centering any fluid power system, valve manifolds improve efficiency, and reduce energy costs. Here are a few more benefits of valve manifolds:
- Increased energy efficiency with shorter flow paths that minimize pressure drop and heat.
- Reduced installation costs and fluid connections due to simpler compact design.
- Reduced oil leaks and upkeep with less connection that can fatigue, wear, and loosen.
- Small and compact sizes with cartridge valve design to suit confined spaces.
- Improved overall layout with less cumbersome hoses and fluid connections.

Manifold valves from Fluid Controls
PB Series Pro Bloc manifold
This bloc manifold range is designed to replace conventional multiple-valve installations currently in use for interface with pressure measuring systems. By combining customer specified valves into a single manifold, the PB Series Pro Bloc Manifold ensures that the number of leak paths are reduced, and the mass of the system is lowered reducing the stresses from loading and vibration.
MF Series Mono flange manifolds
This MF Series Mono flange manifold range is designed to replace conventional multiple-valve installations currently in use for interface with pressure measuring systems. By combining customer specified valves into a single manifold, the number of leak paths are considerably reduced, and the mass of the system is lowered reducing the stresses from loading and vibration.
