Description
PEBCO® Positive Seal Valves feature a fully sealed and gasketed design providing self-adjusting seals for material flow. Maintenance is a cinch on these valves, as rear access allows for disc replacement without the need to remove the valve itself. More product info:
- Fully sealed and gasketed design suitable for pressures up to 14.9 psi
- Tapered disc and seat provide optimum, self-adjusting seal up-stream to down-stream
- Cast urethane disc compresses when closed to allow use in liquid and gas applications
- Large rear access cover allows disc replacement without removing the valve from the process line
- Pneumatic or hydraulic actuation provides constant load on sealing surfaces
- Stack two PSVs to create an improvement on the “Double Dump Valve”
Typical applications include:
- Positive shut-off of aerated products beneath silos and fluidized conveyors
- Dust collector/cyclone discharges and pneumatic conveying
- Improved sealing and low maintenance make this an attractive replacement for rotary valves/airlocks
Optional Features:
- Polymer or metallic discs are available for special applications and/or elevated temperatures
- Outboard bearings with adjustable shaft packing for pressurized applications
- Include a spool or “dutchman” between two PSVs to increase throughput
