  • Oil and gas industry, chemical and petrochemical industries, power plants
  • For gaseous and liquid aggressive media that are highly viscous or crystallising, also in aggressive environments
  • Direct connection of pressure measuring instruments to flanged pipelines or vessels without interface valves
  • Shut-off valve with venting function as tapping point for instruments
  • For mounting to level indicators or differential pressure instruments in level measurement

Special features

  • Increased safety with metal enclosed valve seats and double valve body seal
  • High-quality machining guarantees smooth operation with low torque and low wear
  • Leak-tested tightness in accordance with BS6755 / ISO 5208 leakage rate A
  • Customisable arrangement with ball and needle valves
  • Customer-specific measuring arrangement with valves (instrument hook-up) on request


The monoblock has been designed to meet the requirements of the process industry, especially for natural gas and aggressive media applications. The compact design integrates a shut-off valve to separate the process from the instrument side.

For applications with liquid or dirty media, ball valves are recommended due to easy cleaning of the straight-through internal bore.

The one-piece case minimises the number of leakage points and thereby reduces the risk of media escaping into the environment. The valve seat design and the redundant seals

of the valve body ensure high durability and tightness. In case the soft valve seat fails, the metal-to-metal seat will ensure that the valve can still be operated and set to a safe position. The tightness is guaranteed for the connection between the process and the measuring instrument and towards the atmosphere.

The super-finished machining of the internal parts allows a very smooth and precise operation, even at high pressures and after long periods without valve operation. The surface finish helps to prevent corrosion with aggressive media and makes it easier to clean.
