QFF3 3-Valve Manifold with Differential Pressure Gauge

Specification:

Hongji 3-Valve Manifold with Differential Pressure Gauge

The QFF3 3-Valve Manifold with Differential Pressure Gauge is a compact and efficient solution designed for differential pressure measurement, isolation, and monitoring in industrial systems. This integrated unit combines a 3-valve manifold with a precision differential pressure gauge, enabling real-time pressure observation while ensuring safe and stable operation.

Ideal for applications where full venting is not required, the 3-valve configuration offers a cost-effective and space-saving alternative to 5-valve manifolds, without compromising measurement accuracy or reliability.
