2 Valve Manifold For Pressure Gauge

Our 2 valve manifold for pressure gauge is designed to create a compact and dependable interface between a process pipeline and a pressure-measuring instrument. The manifold normally combines an isolation valve with a bleed or vent valve in one machined body. During normal operation, the isolation valve allows process pressure to reach the gauge. When calibration, replacement, or maintenance is required, the operator can close the isolation path and release trapped pressure through the bleed connection before removing the instrument. Compared with an installation assembled from several individual valves, nipples, and fittings, this integrated arrangement shortens the pressure path, simplifies installation, and helps reduce potential leakage points. Two-valve manifolds are commonly used for the isolation, venting, calibration, and maintenance of static-pressure instruments such as pressure gauges, transmitters, and switches.

The value of a 2 valve manifold for pressure gauge is not limited to the number of valves. Reliable field performance depends on the machining accuracy of the internal flow passages, the alignment of the inlet and instrument connections, the sealing condition of the stem, and the compatibility of every wetted component with the process medium. Our factory evaluates these factors together rather than treating the manifold as a collection of standard parts. Connection direction, thread form, body material, vent orientation, handle style, mounting arrangement, and nameplate information can be matched to the customer's gauge or pipeline layout. For distributors, skid builders, instrument suppliers, and maintenance contractors, the 2 valve manifold for pressure gauge provides a practical product platform that can be configured for different markets without losing consistency between repeat orders.

Wenzhou Zhengyi Instrument & Valve Co., Ltd. has focused on instrument valves and industrial pipeline components since 2004. Our production and warehousing area covers approximately 3,000 square metres, supported by an in-house research and development team. CNC lathes, drilling equipment, tapping machines, ultrasonic cleaning equipment, polishing machines, marking equipment, and other production facilities allow us to manage machining, cleaning, assembly, and identification within a coordinated manufacturing process.

OEM and ODM production is available for distributors, equipment manufacturers, engineering companies, and private-label customers. We can evaluate technical drawings, reference samples, connection diagrams, or prototype requirements before confirming the appropriate structure. Sample production is available before mass production. Minimum order quantity and sample-development time are determined according to the actual design, machining difficulty, material requirements, and inspection conditions.

Quality control covers incoming materials, dimensional inspection, machining, assembly, pressure testing, surface examination, marking, and final packing. Every finished product is inspected before packing, and third-party inspection is welcomed when required by the order. Inspection records can be retained for traceability. Our products are covered by a one-year warranty, supported by a dedicated after-sales team for technical questions and quality-related communication.
