Valve Type and Model Number |
Needle Valve
V-82
V-182F
V-8F |
|
V-82: To control cylinder speed.Can also be used as shut-off valve for temporary load holding. 3/8 NPTF female ports.V-182: Same as V-82, but with 1/4 nptf female ports. Also suitable for gauge snubbing (also V-82).V-8F: Like V-82, but with very fine metering for precise flow control.
Not recommended as shut-off valve. |
Snubber Valve
V-91 |
|
V-91: Infinitely adjustable for
metering oil out of a gauge to prevent snapping of gauge pointer when load or pressure is
suddenly released.Also suitable as shut-off valve to protect the gauge during high cycling
applications. 1/2 nptf male and female threads for use with GA-1, GA-2 or GA-4 gauge
adaptors. |
Auto
Damper Valve®
V-10 |
|
V-10:
To be used when gauge pressure must be monitored during high cycle applications. Creates a
flow resistance when load is released suddenly.No adjustments are necessary. 1/2 nptf male
and female threads for use with GA-1, GA-2 or GA-4 gauge adaptors. |
Check Valve
V-17 |
|
V-17: Ruggedly built to resist shock and operate with low pressure drop. Closes smoothly without pounding. 3/8 nptf female ports. |
Pilot Operated
Check Valve
V-42 |
|
V-42: Can be mounted at the cylinder to hold the load in case of system pressure loss. Normally
used with double-acting cylinders where pilot port receives pressure from a Tee-fitting in
the cylinder retract line. 3/8 nptf female ports.Pilot pressure ratio 14% (6,5:1). |
Manually Operated
Check Valve-66
V-66F |
|
V-66:
Used for load holding applications with single and double acting
cylinders. Valve is manually opened to allow oil to flow back to tank
when cylinder retracts.
V-66F: Similar to V-66, but
with very fine metering capability for precise flow control. |
Pressure Relief Valve
V-152 |
|
V-152: Limits pressure developed by
the pump in hydraulic circuit, thus limiting the force imposed on other
components. Valve opens whenever preset pressure is reached.To increase
pressure setting, turn handle clockwise. Includes:
- 3ft return line hose kit
- 3% repeatability
- 800-10,000 psi adjustment range
|
|
Sequence Valve
V-161 |
|
V-161:
To control oil flow to a secondary circuit. Flow is blocked until system pressure rises to
the V-161 setting. When this pressure level is reached, the V-161
opens to allow flow to the secondary circuit. A pressure differential
is always maintained between the primary and secondary circuit. Min.
operating pressure: 2000 psi |
