Valve Maintenance and Products

Valves 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 cleans and coats the sealing surfaces of the gate and seat, and provides lubrication protection to these critical surfaces as they interact with each other under high contact pressure.

Valve sealing performance is highly dependent on the condition of the sealing surfaces of the seat. An effective Valve Lubricant also has the ability to improve the tightness of sealing surfaces with minor damage (light scoring and scuffing), Lubsur® Valve Lubricants have a well proven track record in this area.

Whether servicing a single wellhead, or an entire field, valve maintenance is of critical importance in oilfield production. Scheduled preventative maintenance can add years to the service life of a valve, reduce repair costs and down time, and minimize replacement needs. Without a proper maintenance schedule, valves can corrode, fail to operate, and ultimately cause loss of product. Scheduled maintenance will prevent: Rusting stem threads, drying and hardening of stem packing, build up of dirt, rust, slag, etc., restricted gate travel, internal corrosion, sealing failure.
