SF-2B 3 way instrument manifold valve stainless steel

Detailed Product Introduction

The SF-2B series integrated 3-way stainless steel instrument manifold valve is a high-performance fluid control component engineered to optimize the installation, operation, and zero-point calibration of differential pressure instruments. CNC-machined from a single block of high-density bar-stock stainless steel, this robust unit integrates two primary process isolation/block valves and one central equalization valve into a unified structural body. The valve assemblies are fitted with protective, functional color-coded dust rings (Red for block/isolation service and Blue for the equalization loop) attached to ergonomic metal T-handles to eliminate operational risk in the field. By facilitating secure process isolation and precise instrument equalization prior to maintenance or testing, it significantly minimizes downtime and guarantees a leak-free mechanical environment for critical automated process loops.
