| Fuel, Gas & Oil Motorized Valves |
| Electro-hydraulic motor operated valves to
handle your combustion system needs. These valves are available in 2-way
normally closed, manual reset and 3-way diversion. ASCO valves are available in
bronze, aluminum and cast iron. Features include pipe taps, visual indication,
proof of closure, leading agency approvals and pipe connections from 3/4” to
6”. Most valves are rated for -40ºF service for outdoor installation in frigid
climates |

| 2-Way-Normally Closed Gas Valves |
| AH Hydromotor Actuator with V710 Aluminum
Body Gas Valves
|
| AH Series Actuator
(Used w/V710 gas valve body) |
 |
Push-type self-contained electrohydraulic linear
actuators. Used with V710 gas valve bodies through 4" pipe size to provide
on-off, manual reset, low-high-off and modulating-off control of main gas lines
to industrial and commercial burners. Power interruption fully closes the valve
in one second or less. |
|
| AH2 On-Off Actuator
(Used w/V710 gas valve body) |
|
Actuator extends when powered and retracts by spring force
(in less than 1 sec) when power is removed. |
|
AH2 Manual Reset
Actuator
(Used w/V710 gas valve body) |
 |
A toggle switch must be manually operated to allow the
powered actuator to extend and latch at full stroke. Actuator retracts by
spring force (in less than 1 sec) when power is removed. |
|
AH4 Low-High-Off
Actuator
(Used w/V710 gas valve body) |
|
This three-position actuator features an electronic
controller for accurate positioning. The low-fire position is factory set at
the midpoint, but can be field adjusted to any position up to 100% of stroke.
Actuator shaft travels to the low-fire position when powered and travels to the
high-fire position when an external switch completes the high-fire controller
circuit. Actuator returns to the low fire position when the circuit is open.
Actuator retracts by spring force (in less than 1 sec) when power is removed. |
|
AH8 Modulating-Off
Actuator
(Used w/V710 gas valve body) |
|
This actuator features a low-fire adjustment up to 100% of
its stroke and also contains control circuitry which responds to an external
135 ohm potentiometer, a 4-20 mA signal or a 1-5 VDC signal to adjust the shaft
to any point between low-fire and fully open (high-fire) position. Actuator
retracts by spring force (in less than 1 sec) when power is removed. |
|
V710 Series
(Used w/AH Actuator) |
 |
The V710 valve is a push-to-open type body for on/off or
proportional control when mounted to an AH Hydramotor actuator. The V710 valve
body is available in four trim styles: quick opening, quick opening w/ valve
seal overtravel, linear and linear w/ valve seal overtravel. Aluminum body.
3/4" thru 3" pipe size, cast iron body 4" pipe size. |

|
|
| 2-Way-Normally Closed Oil Valves |
| Series HOV1
|
 |
These bronze body globe type, teflon seated, 300 psi fuel
oil shutoff valves are ideal for large oil fired commercial and industrial
boilers and process heating applications. Pipe connections from 1/2" to 1".
These valves close in less than 1 sec when power is removed. |
| 3-Way-Normally Closed Oil Valves |
| Series HOV13
|
 |
