This remote-mount instrument manifold integrates isolation and venting functions in a compact structure suitable for industrial measurement systems.
The non-rotating lower stem with hardened surface treatment minimizes friction and wear, while the roll-hardened upper stem thread is isolated from the process medium to extend service life and prevent contamination.
The design ensures:Reliable instrument isolation,Stable pressure measurement accuracy,Long-term sealing durability,Safe operation under high pressure and temperature.
All manifolds are manufactured from high-quality stainless steel or alloy materials and undergo strict pressure testing prior to delivery.
