product introduction

The 5-valve coplanar instrument manifold provides isolation, equalization, and venting functions in a compact direct-mount configuration. Back-seating in the fully open position enhances operational safety and packing protection. A non-rotating hardened lower stem minimizes friction and extends valve service life, while the lubricated upper stem thread is isolated from the process medium. The robust screw-locked handle ensures stable operation. All manifolds are pressure-tested prior to delivery.

Product Description

This 5-valve manifold is designed for direct installation on differential pressure transmitters, providing secure isolation, equalization, and vent control in a single assembly. The compact block body minimizes leak paths and improves structural rigidity. Independent isolation valves and an equalizing valve enable safe calibration, maintenance, and system balancing without process interruption. The durable stem and seat structure ensures long service life under frequent operation cycles in demanding industrial environments.
