Submarine Manufacturing & Products Limited

The Tescom 44-1300 Series, High Flow, High Pressure Regulators are designed to safely reduce inlet pressures of up to 4500 psig and accurately deliver high gas flows throughout the 10-1500 psig outlet pressure range. This self-venting unit can also be furnished as a non-venting regulator for hydraulic applications. A special baffle below the piston provides stable operation and eliminates regulator hunting by preventing sudden and direct inlet pressure upon the sensor. Balanced stem design and soft seated main valve provides bubble tight service.

• Large piston sensor gives excellent sensitivity
• Balanced valve design assures stable downstream pressure
• Large hand knob provides fast low-torque pressure settings
• Self-venting standard
• Available with optional gauge ports
• Dome and Air loaded available (non-venting only)
• Optional 6000 or 5000 psig inlet with 2500 psig outlet

• Operating Parameters: Pressure rating per criteria of ANSI/ASME B31.3
• Maximum Operating Pressure:
  • Stainless Steel Body: 4500 psig
  • Brass Body: 3750 psig
• Outlet Pressure Ranges: 0-300, 0-600, 0-1000 & 0-1500 psig
• Design Proof Pressure: 150 percent of rated pressure
• Leakage: Bubble-tight
• Operating Temperature 1: -15 degrees F to +220 degrees F (-25 degrees C to +104 degrees C)
• Flow capacity 2:
  • 1/4 in. main valve: Cv = 0.8
  • 3/8 in. main valve: Cv = 2.0

1 For extended temperatures from -65 degrees F to +400 degrees F, consult factory.
2 A secondary pressure drop due to the outlet cross-hole can significantly affect the rated flow capacity.

Flow curves should be used for critical sizing applications.
