Although most main gas pressure regulators are modified to accept pilot regulators from the same manufacturer, BelGAS pilot regulators may be used along with other industry models.  The pilot operated BelGAS PL82 and PL83 are designed for seamless compatibility with the company’s P1808 and F289 back pressure relief regulators. They feature aluminum body material and choice of PSIG or WC range. Their robust design allows them to vent continuously when the main valve is either repositioned or in relieving mode. They will not bleed or relieve when pressure values fall below set pressure. The PL82B is designed for more general purpose back pressure relief. As a low bleed pilot, the regulator will only bleed when the valve is repositioned. The PL83 is a high-bleed restriction pilot and lower pressure unit. Options for low, medium and high gain allow for the lowest buildups and fastest response speeds (i.e., high gain is highest speed) and are determined according to the needs of each application.  Please consult the factory for details.

All BelGAS pressure regulators are 100% made in the USA at the company’s state-of-the-art manufacturing facility in Newell, West Virginia. Each product is rigorously tested for durability and performance prior to factory shipment.  They available to customers with lead times as short as 10 business days and are fully supported by an active global sales and distribution network.

Typical applications for the PL82 and PL83 include gas and liquid service, oil and gas separators, and distribution relief for gas distribution systems.
