product introduction

This 2-valve instrument manifold is designed for remote mounting of pressure instruments and gauge applications. The valve features a back-seating function in the fully open position, ensuring reliable isolation and packing protection. A non-rotating lower stem with hardened surface minimizes friction and wear during operation, while the upper stem thread is roll-hardened and isolated from the process medium. Each unit is pressure-tested at rated working pressure before shipment.

Product Description

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.
