Monoblock
Description
The monoblock has been designed to meet the requirements of the process industry, especially for natural gas and aggressive fluid applications. The compact design integrates one or two shut-off valves to separate the process from the instrument side and a vent valve.
The modular monoblock design allows using an arrangement of ball valves and/or needle valves. For applications with liquid or dirty media, ball valves are recommended due to easy cleaning of the straight-through internal bore.
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 is also minimising corrosion with aggressive media and makes it easier to clean.
Special features
- Increased safety with metal enclosed seats and double 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 combination of valves and instruments (hook-up) on request
