Pilot Operated Gas Pressure Regulators




The ‘’F" series pilot loaded, balanced valve design regulators are suitable for low, medium and high outlet pressure. The ‘’F" series regulators are supplied with external sensing lines and are preset for an optional connection to an internal sensing line by the customer.

The special regulator design combined with a balanced valve results in:

* High flow rate coefficient,

* High accuracy, even at maximum flow rates,

* Reduced response times,

* No internal leakage at zero flow rate,

* Periodical maintenance without disassembling the body from the pipework,
