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.
