PRESSURE GAUGESGauge Isolator ValveModel No. GV-4Single StationSpecifications• Push knob to read• Can be locked in actuated position• Panel or in-line mounting• Made of press forged steel• 5800 PSI working pressure• Maximum panel thickness 5 /16"• 1 /4" NPT ports• Viton seals• Compatible with petroleum based fluids andother fluids compatible with Viton seals• Operating temperature -30°F to +240°F(-22C to +115C)Ports: 1 /4" NPTWorking Pressure: 5800 PSIGauge isolators prevent damaging pressuresurges from reaching the gauge except whena reading is required. They help to extendgauge life and maintain accuracy.Panel MountReturn OutletPressure InletGauge Isolator ValveModel # GV-4RThe LENZ Gauge Isolator Valve isa simple effective throttling andshut-off device to isolate and protecthydraulic pressure gauges. It willquickly and positively shut off thegauge from the line pressure or,when partially opened, reduce oreliminate gauge pointer pulsations.The leakproof needle stem isinternally retained.Features:• Steel Construction• 5000 PSI Maximum System Pressure• Viton Seals-Compatible WithMost Fluids• Finger Tip Adjustment and LocknutSiphonsLENZ Siphons should be used toprotect pressure instruments in livesteam service or other hot vaporapplications.The vapor condenses inside the coilof the siphon which prevents the hightemperature vapors from reachingthe sensing element of the pressureinstrument.MODEL NUMBER4-SIP4-SIP-SS8-SIP8-SIP-SSDESCRIPTION1/4" x 1 /4"-MALE (STEEL)1/4" x 1 /4"-MALE (STAINLESS)1/2" x 1 /2"-MALE (STEEL)1/2" x 1 /2"-MALE (STAINLESS)Couplings(to attach pressure gauges to siphons)MODEL NUMBER4-PC4-PC-SS8-PC8-PC-SSDESCRIPTION1/4" x 1 /4"-MALE (STEEL)1/4" x 1 /4"-MALE (STAINLESS)1/2" x 1 /2"-MALE (STEEL)1/2" x 1 /2"-MALE (STAINLESS)Chemical SealsChemical seals also referred to as diaphragmseals, are used to isolate pressure gaugesfrom clogging and /or corrosive media.The upper seal is also filled with siliconefluid. Any pressure applied by the processmedium to the seal diaphragm ishydraulically transmitted to thepressure element of the gauge,thus generating a pressure readingon the pressure gauge.
