Frequently Asked Questions About commercial regulators

• Q: What is the primary difference between a pilot-operated and a direct-operated regulator?

  A: A direct-operated regulator uses the controlled pressure directly on a diaphragm to actuate the valve. A pilot-operated commercial regulator, like the RTJ2-DKQ series, uses a smaller, auxiliary pilot regulator to control the main valve, offering much higher accuracy, faster response, and better stability, especially at higher flow rates and larger pressure drops.

• Q: How often should a commercial regulator be inspected or maintained?

  A: While the RTJ2-DKQ series is designed for low maintenance and a long service life (15-20 years), routine visual inspections are recommended annually. A more thorough preventative maintenance check, including diaphragm inspection and seal replacement, is advised every 3-5 years, depending on the specific application and operating conditions.

• Q: Can the RTJ2-DKQ series handle gases other than natural gas?

  A: Yes, the RTJ2-DKQ series can be configured for various non-corrosive gases such as LPG, propane, and inert gases. For corrosive or specific industrial gases, customized material selection for internal components and seals is available to ensure compatibility and long-term performance.

• Q: What are the key factors to consider when sizing a commercial regulator?

  A: Critical factors include maximum and minimum inlet pressure, desired outlet pressure range, maximum and minimum flow rates, specific gravity of the gas, and upstream/downstream piping configurations. Our technical team can assist with precise sizing calculations to ensure optimal performance.
