Descripción

El FRG- Regulador/Válvula Proporcional Dungs -Roscada has an adjustable setpoint spring and nonadjustable counterspring.

  1. Optional Low fire bypass for ½ in. NPT to 2 in. NPT models. Ideal for low flow or for high turndown applications.
  2. Steady, precise and instantaneous regulation of the outlet pressure.
  3. Connection for air impulse line.
  4. Inlet and outlet ¼ in. NPT test ports on each side.
  5. Factory installed vent limiter. Review applicable codes for vent line requirements.

FRG/6 Spring-loaded ratio regulator/zero governor with adjustable setpoint spring and defined counterspring. Internal sensing of output pressure; air impluse line connection is standard.

Aplicaciones del FRG- Regulador/Válvula Proporcional Dungs -Roscada

  1. El FRG se recomienda para aplicaciones de calefacción industrial y comercial. Es adecuado para gas natural seco, propano, butano, aire y gases inertes. Adecuado para hasta 0.1% en volumen, H2S seco.
  2. Aplicación (regulador de relación) Mantiene una relación constante de gas / aire durante la reducción variando el flujo de gas al quemador en proporción al flujo de aire de combustión. Relación ajustable para el exceso de gas o aire.
  3. Aplicación (Gobernador cero) Controla el combustible reduciendo la presión de gas entrante a cero o ajustable ligeramente por encima o por debajo de la presión atmosférica.

📋 Especificaciones básicas

Pipe thread (NPT) 1/2″ 3/4″ 1″ 1 ¼” 1 ½” 2″ 2 ½” 3″
Max. operating pressure 7 PSI (500 mbar) UL, FM  5 PSI (360 mbar) CSA
Max. body pressure 15 PSI (1000 mbar)
Optimal inlet pressure range Ratio regulator = 3 to 82 in. W.C. (7 to 200 mbar) Zero Governor = 3 to 20 in. W.C. (7 to 50 mbar) with 10:1 turndown Zero Governor = 3 to 82 in. W.C. (7 to 200 mbar) with 3:1 turndown
Output pressure range Ratio regulator output = 0 to 60 in. W.C. (0 mbar to 150 mbar) Zero Governor output= -2 to 2 in. W.C. (-5 mbar to 5 mbar)
Materials in contact with gas Housing: Aluminium
 Seals and diaphragms: NBR
Ambient temperature +5°F to +160 °F for up to 7 PSI for regulating behavior (+/- 10% of setpoint). -40 °F to +160 °F: Diaphragms are suitable for the low temperature, but there may be out of range regulating behavior. CSA Certified for -40 °F to +160 °F for up to 5 PSI.
Installation position Regulator dome vertically upright or horizontally.
Test ports / Pilot gas connections ¼ in. NPT on both sides of the inlet section and ¼ in. NPT on both sides of the outlet section. Taps/connections only on one side when low fire bypass is used.
Low fire Bypass (Optional) Field mountable low fire bypass: ½ in. NPT to 2 in. NPT on either side of housing
Vent line connection / air impulse line connection / vent limiter • The vent line connection/air impulse line connection is G ¼“ for FRG‘s up to 1“ NPT, and it is G ½“ for FRG‘s 1 ¼ to 3“ NPT. A G thread to NPT thread field mountable adapter is available.
• For gas/air ratio applications at pressure ratio of approximately 1:1, use the existing connection as pressure connection for air impulse line / blower pressure, and at low fire, the air impulse line pressure shall be between 0.2 to 1.0 in WC.
• The FRG/6 also has a factory installed vent limiting device, which limits the escape of gas to less than 0.5 CFH @ 5 PSI in case atmospheric diaphragm ruptures. Venting required unless otherwise accepted by the authority having jurisdication.
