product introduction

The 2-valve direct mount coplanar instrument manifold is designed for compact installation on pressure transmitters. Back-sealing in the open position protects packing integrity and improves long-term reliability. The two-piece stem design allows axial movement without rotation at the lower stem, reducing wear on packing and valve seats. A screw-locked handle provides secure operation, while isolated stem lubrication prevents contamination of the process medium. All units are pressure-tested before shipment.

Product Description

This direct-mount 2-valve instrument manifold integrates isolation valves in a compact coplanar body for pressure transmitter mounting. Back-sealing in the fully open position protects packing integrity and improves long-term sealing reliability.

The two-piece stem structure allows axial movement of the lower stem without rotation, reducing friction on packing and minimizing seat wear. A screw-locked handle ensures secure operation, while isolated stem lubrication prevents contamination of the process medium.

All manifolds are pressure-tested before shipment to ensure sealing performance and operational safety in industrial service.
