The V91 Hydraulic Snubber Valve is used to prevent damage to a hydraulic gauge. It provides adjustable metering of oil from the gauge offering protection when the load or pressure is suddenly released. 
The V91 can also be used as shut-off valve to protect pressure gauges used for high-cycle applications. 
The valve includes 1/2" NPTF male and female threads allowing connection to Enerpac GA1, GA2 or GA4 gauge adaptors.
