This 3-valve instrument manifold is designed for direct installation on non-flanged differential pressure transmitters. The back-sealed valve structure enhances isolation reliability during maintenance and calibration. A non-rotating hardened lower stem reduces packing wear and internal friction. The roll-hardened upper stem thread is lubricated and isolated from the process fluid to ensure durability and cleanliness. Each unit is factory-tested at rated pressure before delivery.
