product introduction

This 3-valve coplanar instrument manifold is used for direct mounting on differential pressure transmitters. It features a back-seated valve design to enhance sealing performance during maintenance. The hardened non-rotating lower stem reduces friction and wear during repeated operation cycles. The upper stem thread is roll-hardened and isolated from process media to maintain cleanliness and durability. Each manifold is factory-tested under rated working pressure to ensure sealing reliability.
