ClareTech PVS – Plug Valve Sealant
Plug valves play a critical role in ensuring flow control in high pressure fluid systems. Valve failures which compromise the efficiency of an operation can result in unexpected downtime, production or process time losses and can increase operational costs significantly.
Plug valve sealant and maintenance
Effective maintenance of plug valves is critical and a significant part of valve maintenance involves greasing the valves to properly seal and lubricate them and provide sustained operating protection.
RS Clare is a global market leader in specialty valve lubricants and ClareTech PVS is the latest high performing valve grease designed specifically for plug valve applications. It has been developed in response to feedback from the market that the ‘stick’ type sealants, which are commonly used, sometimes do not provide all the necessary attributes required to protect, seal and adequately lubricate the valve’s internal components.
Developed as an alternative to 'stick' type sealants that don't always adequately lubricate the valve's internal components:
- Highly adhesive to ensure the lubricant remains in attached to the internal surfaces of the valve and its sealing componenets, even when exposed to fluid flows at high pressures, high temperatures and high flow rates.
- Does not harden or dry out after periods inside the valve. ClareTech PVS will retain its consistency to provide full lubrication to the valve between greasing intervals.
- ClareTech PVS offers optimal viscosity for smooth pumpability across a wide temperature range, while also reducing valve torque during the opening and closing of the plug valve.
Increased sealing capacity
ClareTech PVS has enhanced sealing capability compared to some commonly selected grades of stick sealants, as proven in back to back testing during high pressure valve testing program (report available). This is both the case in new valves, where the seal components are in perfect condition, but more importantly when there is damage to the faces of the seal components. Debris or hard contaminants within the flowing fluids, and poor lubrication can cause abrasive and adhesive wear on the plug and seats components.
Such damage creates leak pathways resulting in the valve unable to reliably shut-off and maintain a leak tight seal. ClareTech PVS can be injected in the field to assist a compromised plug valve generate an integral seal, potentially saving significant downtime.
Coating of internal valve components
The consistency and texture of ClareTech PVS is a degree softer than the typical stick sealants, which have a harder or firmer texture. When PVS is injected into the plug valve it flows exceptionally well through the channels to coat all the surfaces of the plug and seats, creating an excellent lubricating and sealing film.
Hydrocarbon & chemically resistant
Fully resistant to produced liquid and gaseous hydrocarbons and chemicals such as H2S, CO2 and water and chlorides. ClareTech PVS is also fully resistant to a range of injected chemicals – please consult RS Clare for specific technical information.
