The EF-2 two-valve manifold is an integrated instrument manifold specifically designed for use with pressure transmitters, pressure gauges, and differential pressure transmitters, integrating two isolation valves into one compact body. Through precision internal flow path design, it enables connection, isolation, and draining/venting operations between the instrument and process pipelines. Featuring threaded or flanged connections (depending on model configuration), reliable sealing, and easy installation, this manifold is primarily used for pressure instrument root isolation, online calibration, and draining/venting. It serves as a critical instrument accessory in industries such as petrochemical, power generation, metallurgy, and pharmaceuticals, ensuring safe isolation and precise control of measurement systems.

1. Integrated and compact design: Two shut-off valves are integrated into the same valve body, with a compact structure that reduces pipeline joints and lowers the risk of leakage.

2. Easy to operate: Through the coordinated operation of two valves, the instrument can be quickly put into operation, isolated, and discharged without the need to disassemble the instrument.

3. Multiple connection methods: Internal thread, external thread, or flange connection can be selected according to the working conditions to adapt to various instrument interfaces.

4. All stainless steel material: The valve body and internal components are made of 304/316 stainless steel, which has excellent corrosion resistance and is suitable for corrosive media and harsh environments.

5. Reliable sealing: The valve stem is filled with PTFE or flexible graphite, combined with a hardened valve disc, which has a long opening and closing life and low risk of leakage.

6. Strong pressure resistance: The valve body structure has high strength and is suitable for medium and high pressure working conditions, meeting the safety requirements of process control systems.
