76F-108-01 Shut off Valve 2 (76F-108-01): International Buyer's Guide to Gas Shut-Off Valve Actuators
Table of Contentsexpand_more
The 76F-108-01 Shut off Valve 2 (76F-108-01) refers to a gas shut-off valve configuration that pairs an ASCO-compatible valve body with a REDHAT actuator. Buyers should verify the valve body series (158 or V710), the required control signal (on/off or High/Low/Off), and whether a proof-of-closure switch is needed for safety interlocks.
What is a 76F-108-01 Shut off Valve 2 (76F-108-01)?
A 76F-108-01 Shut off Valve 2 (76F-108-01) is a gas shut-off valve assembly used to isolate or regulate fuel gas flow in industrial heating and combustion systems. It typically combines a valve body with a REDHAT actuator that drives the valve open or closed in response to an electrical control signal.
In practice, the 76F-108-01 designation is often used as a line item or assembly reference for a valve-plus-actuator package rather than a single standalone component. The actuator is the serviceable and replaceable element, and REDHAT actuators are commonly specified for ASCO Series 158 and V710 gas shut-off valve bodies.
Quotable definition
A 76F-108-01 Shut off Valve 2 (76F-108-01) is a gas shut-off valve assembly in which a REDHAT electric actuator operates an ASCO-compatible valve body, providing on/off or High/Low/Off control of fuel gas in industrial heating systems, typically on 120 V AC at 50 Hz or 60 Hz with a NEMA 1 indoor rating.
How does a gas shut-off valve actuator work?
The actuator receives an electrical control signal and moves the valve stem to open, close or modulate gas flow. On/off actuators provide two positions, while High/Low/Off actuators add an intermediate flow position for staged firing. A proof-of-closure switch confirms the valve has reached the closed position, which is important for safety interlocks and burner management systems.
REDHAT actuators for ASCO Series 158 and V710 bodies are designed for indoor general-purpose environments with a NEMA 1 rating. They are commonly used in industrial heating systems where reliable gas flow regulation and safe shut-off are required.

Which actuator type suits your application?
Choose an on/off actuator when the burner or appliance requires simple open/closed gas control. Choose a High/Low/Off actuator when staged firing or two firing rates are needed. Choose a High/Low/Off actuator with proof of closure when the safety system must verify the closed position before allowing ignition or another sequence step.
For ASCO Series 158 bodies, the on/off and High/Low/Off REDHAT actuators are direct options. For ASCO Series V710 bodies, the High/Low/Off actuator with proof of closure is the matching choice. Always confirm the valve body series before ordering, because actuator mounting and linkage differ between series.
Selection criteria for International buyers
- Valve body series: Confirm whether the existing or new valve body is ASCO Series 158 or V710. Actuator compatibility is series-specific.
- Control signal: Match the actuator to the burner management or control system output: on/off or High/Low/Off.
- Proof of closure: Specify a proof-of-closure switch if the safety interlock requires verified closed position.
- Supply voltage and frequency: The listed REDHAT actuators use 120 V AC. Verify that 50 Hz or 60 Hz supply and control voltage match the site supply; step-down or control transformers may be needed in 230 V AC markets.
- Environment: NEMA 1 is for indoor general-purpose use. For outdoor or washdown areas, consider additional enclosure protection.
- Duty cycle and opening time: Fast-opening actuators suit applications requiring quick response; standard opening suits normal heating control.
- Spare parts and lead time: Plan for actuator replacement as a wear item and confirm availability before maintenance windows.
Product selection ladder: REDHAT actuators from 3G Electric
| Model | Best for | Control signal | Valve body | Proof of closure | Supply |
|---|---|---|---|---|---|
| REDHAT On/Off Actuator for ASCO Series 158 | Simple open/closed gas shut-off | On/off | ASCO Series 158 | No | 120 V AC, 50/60 Hz |
| REDHAT High/Low/Off Actuator for ASCO Series 158 | Staged firing with fast opening | High/Low/Off | ASCO Series 158 | No | 120 V AC, 50/60 Hz |
| REDHAT High/Low/Off Actuator with Proof of Closure for ASCO V710 | Safety-critical shut-off with position feedback | High/Low/Off | ASCO Series V710 | Yes | 120 V AC, 50/60 Hz |
Step up the ladder when your application requires staged firing or safety interlock feedback. The on/off actuator is the simplest choice for basic shut-off, while the High/Low/Off models add control flexibility. The V710-compatible unit with proof of closure is the most feature-rich option for safety-critical installations.

Frequently asked questions
What is the 76F-108-01 Shut off Valve 2 (76F-108-01) used for?
It is used to isolate or regulate fuel gas in industrial heating and combustion systems. The assembly typically includes an ASCO-compatible valve body and a REDHAT actuator, providing on/off or High/Low/Off control for burner management and safety shut-off applications.
How do I choose between on/off and High/Low/Off actuators?
Choose on/off for simple open/closed gas control. Choose High/Low/Off when the burner requires staged firing or two flow rates. If the safety system needs verified closed position, select a High/Low/Off actuator with a proof-of-closure switch.
Can I use these 120 V AC actuators in 230 V AC markets?
The listed REDHAT actuators are rated for 120 V AC at 50 Hz or 60 Hz. In 230 V AC markets, a suitable control transformer or a different actuator voltage variant is required. Always confirm the site supply and control circuit voltage before ordering.
