GATE VALVE GREASE

Gate Valve’s require periodic maintenance to inject a lubricant into the valve cavity. The purpose of the lubricant is to occupy the empty space in the valve cavity, displacing aggressive fluids and contaminants and acting as a barrier to prevent further ingress. The lubricant in the cavity wipes clean and coats the gate and seat seal surfaces, and provides lubrication protection to these critical surfaces when they interface with each other under high contact pressure.

The sealing performance of the gate valve relies heavily upon the condition of the gate and seat sealing surfaces. An effective Valve Lubricant also has the ability to provide sealing enhance to seal surfaces with minor damage (light scoring and galling), RS Clare’s Valve Lubricants have a well proven track record in this area.
