WIKA Valve Manifold (IV30, IV31, IV50, IV51)

3-, 5-valve manifold for differential pressure measuring instruments


  • Shut-off, pressure compensating, purge and vent valves for differential pressure measuring instruments
  • For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive environments
  • Process industry: Oil & gas, petrochemical, chemical industries, power generation, water and wastewater

Special features

  • Low-wear design due to non-rotating spindle tip in the bonnet
  • Low torque and smooth operation of valve handle even at high pressure
  • Enhanced safety due to blow-out proof bonnet design
  • Customer-specific combination of valves and instruments (hook-up) on request
  • Standardised centre distances of 37 mm and 54 mm, suitable for WIKA differential pressure gauges and commonly used process transmitters

3-valve manifold, models IV30 and IV31
The 3-valve manifold consists of two shut-off valves and one pressure compensating valve. The shut-off valves separate the process from the differential pressure measuring instrument. The pressure compensating valve enables the compensation between ⊕ side and ⊖ side to avoid one-sided overpressure during commissioning and operation.

5-valve manifold, models IV50 and IV51
Compared to the 3-valve manifold, the 5-valve manifold is equipped with two additional vent valves. One vent valve per pressure side allows operators the targeted venting of one or both pressure sides of the measuring arrangement.


Through the non-rotating spindle tip, the wear of the sealing elements is reduced. This results, particularly with frequent opening and closing, in a noticeable increase in the service life of the valve manifold.

Through the blow-out proof design of the valve, working safety is improved, especially in applications with high pressure loading.

As an option, WIKA offers the professional assembly of valves and pressure measuring instruments and also other accessories into a ready-to-install solution, also known as a hook-up. To ensure the performance of the complete system, an additional leak test is carried out on the hook-up.
