ASCO and ASCO-General Controls offer a wide range of solenoid and
motor operated combustion valves from stock as well as specialized
products for every need. Normally Open or Normally Closed
operation. Leading agency approvals such as UL, FM, AGA, CGA and
CSA.
Pilot Gas Shutoff 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 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 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 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 Valves
Once tripped by power interruption, these gas shutoff valves must
be manually reset prior to recycling the system.
Direct Acting Fuel Oil 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 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. [ Steam

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
Visual Indication
ASCO's optional visual indicator meets FM and NFPA requirements for quick
determination of a valve's open or closed position.
Proof of Valve Closure
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.
