The ASCO™ HV285 Series Solenoid Valve is a low-temperature gas shutoff valve designed for reliable on-off control of fuel gas in commercial and industrial burner systems. Its stainless-steel construction, resilient soft seating, and robust solenoid design provide dependable operation and tight shutoff in demanding gas applications.
Designed to operate in ambient temperatures as low as -40°F (-40°C), the HV285 is well suited for installations exposed to cold operating conditions. The valve provides normally closed operation, zero minimum pressure differential, and up to 50 psi maximum operating pressure differential, making it a practical choice for a variety of fuel-gas control applications.
The ASCO HV285 also offers options for explosion-proof and watertight solenoids, supporting installations where environmental conditions or hazardous-location requirements must be considered. It meets applicable automatic gas valve safety standards and NACE MR-0175 metallurgical requirements, making it particularly well suited for demanding industrial fuel-gas applications.
Advantages
HV285 Series Solenoid Valve Advantages
Reliable Low-Temperature Operation
The ASCO HV285 is specifically designed for fuel-gas shutoff applications where low ambient temperatures can affect conventional valve performance. Its operating range extends from -40°F to 125°F (-40°C to 52°C), allowing it to operate reliably across a broad range of environmental conditions.
Tight Fuel-Gas Shutoff
A resilient soft-seat design helps provide tight shutoff when the valve is de-energized. This makes the HV285 suitable for applications where dependable isolation of fuel gas is an important part of burner system operation.
Zero Minimum Pressure Differential
The HV285 can operate with zero minimum pressure differential, providing flexibility when system pressure conditions vary. The valve supports a maximum operating pressure differential of up to 50 psi, depending on the specific configuration.
Stainless-Steel Construction
The stainless-steel body provides a durable construction for demanding fuel-gas service. Internal materials are selected for low-temperature operation, while the valve's construction also meets the metallurgical requirements of NACE MR-0175.
Hazardous-Location Options
Explosion-proof and watertight solenoid options are available for installations where additional environmental protection or hazardous-location suitability is required. The appropriate valve and coil configuration should be selected according to the installation requirements.
Applications
HV285 Series Solenoid Valve Applications
Commercial and Industrial Fuel-Gas Control
The ASCO HV285 is designed for on-off control of fuel gas in commercial and industrial burner systems. Its low-temperature capability makes it particularly useful where gas shutoff equipment may be exposed to cold ambient conditions.
Common applications include:
- Industrial gas burners
- Commercial heating equipment
- Furnaces
- Boilers
- Ovens
- Kilns
- Gas-fired process equipment
- Fuel-gas trains
- Outdoor or cold-environment gas installations
- Industrial equipment requiring dependable fuel-gas isolation
The valve is intended for fuel-gas shutoff rather than general-purpose fluid control, making proper application and media compatibility important during valve selection.
Configurations
HV285 Series Solenoid Valve Configurations
Valve Function
The HV285 Series uses a 2-way, normally closed configuration. The valve opens when the solenoid is energized and returns to the closed position when de-energized.
Connection and Size Options
The HV285 product family is available in configurations with NPTF connections. Specific pipe sizes and configurations should be verified against the required ASCO part number rather than assuming that every size listed for the broader ASCO gas-valve portfolio applies to the HV285.
Electrical Options
Standard solenoid voltages include:
- 12 VDC
- 24 VDC
The available coil construction should be selected according to the control voltage, installation environment, and required approvals.
Environmental Options
Depending on the selected configuration, the HV285 can be specified with solenoid options intended for demanding environments, including explosion-proof and watertight constructions.
Safety and Compliance
The HV285 Series is designed to meet applicable requirements associated with automatic gas valves and safety shutoff applications. The product information identifies compliance with:
- Automatic Gas Valves Z21.21 / CSA 6.5
- ANSI/ISA-12.27.01 single-seal requirements
- NACE MR-0175 metallurgical requirements
Exact certifications and approvals should be confirmed for the selected configuration before ordering.
