Send Enquiry

The ULR-1 is a high-performance, pressure-loaded, diaphragm-type, flow-to-open pressure reducing regulator. It features an internal pressure balancing piston cylinder that delivers high flow capacity and the ability to handle high pressure drops. The innovative trim design allows the same unit to cover a broad range of pressure settings. The ULR-1 regulator’s performance meets or exceeds that of competitive pressure-loaded or pilot-operated designs. Additionally, it includes a back pressure regulator or “unloader” that is piped to the top of the dome and is set to control the outlet pressure of the pressure reducing regulator.

Specifications

Regulator Type: Pressure-loaded, diaphragm-type, flow-to-open
Body Sizes: 1/2″ – 4″ (DN15 – 100)
Materials: Five basic materials with multiple trim material combinations
Shutoff Class: Class IV or VI inboard leakage rates
Pressure Control: Highly accurate, with almost zero “droop effect”
Guiding: Heavy-duty, top and bottom guided to maintain stability

Technical Data

Flow Capacity: High, with pressure balancing that allows for higher inlet pressures
Pressure Range: Broad range due to internal trim design
Sensitivity and Stability: Unmatched due to absence of a range spring in the design
Trim Design: Cage-contained with easily removable quick change trim
Rangeability: Up to 2000:1, thanks to close tolerances, balanced trim, and a variety of elastomeric and metallic diaphragms and soft seats
Failure Mode: Fails closed on loss of loading pressure
Service: Designed for gaseous services, suitable for atmospheric industrial gases

Advantages

High Flow Capacity: Accommodates high pressure drops and offers the highest capacity in the industry.
Compact Design: Allows for smaller body sizes than competitors in most applications.
Accurate Pressure Control: Ensures minimal “droop effect” for consistent outlet pressure.
Durability: Heavy-duty guiding enhances stability and extends diaphragm life.
Versatility: The design covers a broad range of pressure settings with multiple methods of pressure loading and trim material combinations.

Industries

Industrial Gas: Ideal for atmospheric gases like GN2, GOX, Ar, He, H2, CO2.
Utilities: Can be used as a utilities air regulator.
Gaseous Service Applications: Suitable for various industrial processes involving gases.

Applications

Atmospheric Industrial Gases: Excellent for GN2, GOX, Ar, He, H2, CO2.
Utilities Air Regulation: Effective in controlling air pressure in utility systems.
General Gaseous Services: Versatile for use in a wide range of gaseous service applications across different industries.
