The J123 is a spring loaded distribution and industrial regulator that can also be operated by auxiliary systems and is suitable for use as a monitor or active regulator. It is designed for use in installations complying with the requirements of BGC/PS/E26 (formerly DIR6) and IGE/TD/10.
All units are suitable for operation on natural, liquefied petroleum and manufactured gases and can be installed in horizontal or vertical pipelines. The regulator is connected with an external impulse connection.
High sensitivity is assured by a high pressure rolling secondary diaphragm. A valve travel indicator and breather hole dust cap are fitted as standard on all units.
The J123 has been designed on a modular basis which allows the regulator mechanism to be removed without disturbing the pipework.
