MAXITROL

MAXITROL lever-acting regulators (e.g., 325 series) use a lever mechanism to directly open or close the valve based on downstream pressure changes. They are typically used for moderate flow applications (up to ~2,000,000 BtuH) and provide a simple, cost-effective solution. Double-diaphragm regulators (e.g., 210D, R500S) incorporate a balanced valve design with two diaphragms to minimize the effect of inlet pressure variations on outlet pressure. This allows for higher flow capacities (up to 8,000,000 BtuH) and tighter control, making them suitable for larger commercial or industrial burners where stability is critical.

MAXITROL regulators are designed for use with natural gas, LP gas (propane), and manufactured gas. The specific gas type is determined by the orifice size and spring configuration. For example, models with the suffix "-NG" (e.g., 325-7AL-1010-NG02) are factory-set for natural gas, while LP gas versions are available. Always verify the gas type and inlet pressure range with the model's specifications before installation.

Standard MAXITROL lever-acting regulators (325 series) are rated for a maximum inlet pressure of 5 psi (345 mbar). Higher inlet pressures may require a different regulator series or additional upstream pressure reduction. For applications exceeding 5 psi, consult the product data sheet or contact 3G Electric for alternative models.

Some MAXITROL models, such as the RV48-66-0064 poppet regulator, carry CE and CSA certifications. Certification status varies by model and production date. For specific compliance requirements (e.g., Singapore's SPRING or international standards), check the product label or request certification documentation from 3G Electric. The company ships globally and can provide technical data sheets for each model.

Selection depends on three factors: gas capacity (BtuH), inlet pressure, and desired outlet pressure. MAXITROL regulators are rated for specific BtuH ranges at a given pressure drop. For example, the 325-3L-33-NG01 handles 402,500 BtuH, while the 210D-1010-0018 handles 8,050,000 BtuH. Also consider connection size (NPT) and gas type. Use the manufacturer's sizing charts or consult 3G Electric for assistance.

MAXITROL regulators are generally field-serviceable. Replacement parts such as diaphragms, springs, and valve seats are available for many models. However, some lower-cost models may be considered disposable. For lever-acting and double-diaphragm types, 3G Electric can supply service kits. Always refer to the installation and maintenance manual for your specific model.
