Two Valve (Three-Way) Manifold for Pressure Instruments
Arrotop is a leading manufacturer and exporter of Two Valve (Three-Way) Manifolds, specially designed for use with static pressure instruments like pressure gauges, transmitters, and switches. These compact valve assemblies are engineered for safe and efficient isolation and venting of pressure lines, offering long-term reliability in critical measurement systems.
Our two-valve manifolds are commonly used in systems where accurate pressure readings and safe calibration or maintenance are essential, without interrupting the process.
What is a Two Valve (Three-Way) Manifold?
A Two Valve (Three-Way) Manifold consists of one block valve and one bleed valve in a single body. This configuration allows for:
- Isolation of the instrument from the pressure source, and
- Bleeding of trapped process pressure for safe removal or calibration of the device.
The term “three-way” typically refers to the flow path and connections, not the number of valves. It enables connection of one inlet and two outlet ports (or vice versa), giving flexibility in instrument setup.
