R Series – Gas Pressure Regulator, Threaded Connection PS: 16 bar
Direct-acting, spring-loaded regulation with threaded connections, rated PS 16 bar.
The R Series is a direct-acting, spring-loaded gas pressure regulator designed and manufactured according to the 2014/68/EU Pressure Equipment Directive, EN 334 and EN 14382. A fail-open design with a balanced valve or ratio system, it holds outlet pressure across a wide regulation range and seals fully at zero flow, making it the threaded-connection workhorse for service lines and industrial installations up to 16 bar.

Frequently asked questions
What engineers most often ask when specifying this equipment.
Outdoors, the bonnet vent can usually discharge to atmosphere directly. Indoors, fit the vent-limiter option or pipe the vent to a safe external location as required by local code.
