| Pilot Gas Shutoff Combustion Valves |
|
 |
 |
| These valves control gas flow to the pilots of domestic, commercial and industrial burners. In event of power interruption, they close automatically
|
|
| Direct Acting Gas Shutoff Combustion Valves |
|
 |
|
| These direct acting valves provide positive shutoff on main gas lines of domestic and commercial burners. In event of power interruption, they close automatically. |
|
| Pilot Operated Gas Shutoff Combustion Valves |
| These internal pilot operated diaphragm valves are used where high flow and low pressure drop are required on main gas lines of commercial and industrial burners. In event of a power interruption, they close automatically. |
|
| Normally Open Gas Vent Combustion Valves |
|
 |
|
| These vent valves are used in commercial and industrial gas burner systems, mounted in the main or pilot gas lines between the blocking (gas shutoff) valves. The line must be vented to outside atmosphere. In event of a power interruption, these valves open automatically. |
|
| Manual Reset Combustion Valves |
|
| Once tripped by power interruption, these gas shutoff valves must be manually reset prior to recycling the system. |
|
| Direct Acting Fuel Oil Combustion Valves |
|
| These 2 and 3 way valves provide positive shutoff of fuel oil in industrial and commercial oil burner systems. They are suitable for main line and pilot line applications. In event of power interruption, these valves close automatically. |
|
| Hot Water and Steam Combustion Valves |
|
| ASCO offers a wide range of rugged, direct acting or pilot operated valves for heavy duty hot water and steam control applications. Available for normally open or normally closed operations. Stainless steel or brass bodies. |
|
| ASCO-General Controls Hydramotor® Actuator |
|
| The Hydramotor Series of Linear and Rotary Actuators feature a completely self-contained, hydraulic power system that has been integrally coupled to a hydraulic cylinder. The positive, firm positioning actuators are ideal for providing efficient and precise control of valves, dampers, louvers, and a wide variety of other equipments requiring operating thrust or torque of up to 4,000 lbs. (1,800 kg.) |
|
| Fire Suppression Systems Components |
|
 |
|
|
| These mechanically actuated shutoff valves are available in "pull to close" (PTC) or "release to close" (RTC) configurations. They are typically used as a final control element in an automatic fire suppression system or as a manual emergency shutoff to limit loss in event of fire. |
|
| Optional Features of Combustion Valves |
| Visual Indication |
Proof of Valve Closure |
| ASCO's optional visual indicator meets FM and NFPA requirements for quick determination of a valve's open or closed position. |
ASCO valves with optionals proof of valve closure features overtravel seal and meets UL, FM, NFPA, AGA and CGA requirements for electrical interlock of valve position. |
