Installation Direction of Filter Regulator on Pneumatic Valve

The filter regulator, as an optional accessory for pneumatic valves, serves to filter the air supply and adjust pressure, playing an indispensable role in instrument valves. However, many field personnel are unaware of the correct installation method for filter regulator. Conventional valve manufacturers default to installing the filter regulator based on horizontal valve orientation. If an instrument valve is to be installed on a vertical pipeline, the installation direction must be specified in advance so that VATTENVALVE can modify the configuration before shipment.

This issue requires attention to numerous details from design through construction and installation.

1. During the design phase, the flow direction of pipes and valve positions must be precisely marked, with vertical orientations clearly indicated.
2. During on-site installation, many components are found installed backwards (primarily because ISO standards lack flow direction indicators). Additionally, improper installation by operators contributes to this issue.
3. In locations like South Korea, the United States, and Australia, local labor costs are prohibitively high.Never leave issues that can be resolved during design to be addressed on-site.

What are the consequences of incorrectly installing filter regulator?

Failure to install the filter according to standards may prevent automatic drainage, allowing contaminants to enter the cylinder and disrupt normal operation. This can also cause unstable pressure or significant fluctuations.

Therefore, proper installation prevents numerous complications.
