The 5-valve direct mount instrument manifold is engineered for direct installation on non-flanged differential pressure transmitters used in demanding process industries. The manifold combines two isolation valves, one balance valve, and two bleed /test valves to provide full pressure control during operation, calibration, and maintenance.
The back-seating valve design enhances sealing reliability when fully open, protecting packing integrity. A two-piece stem with a hardened non-rotating lower section minimizes friction and wear, ensuring long-term stability. The roll-hardened upper stem thread is lubricated and isolated from process media, improving durability and cleanliness.
Each manifold is precision-machined from high-strength material and factory pressure-tested at rated working pressure before shipment to ensure safety and leak-tight performance.
