Valve Sealant 701
The Valve Sealant 701 and 701-L provides superior sealing performance for leaking gate valves. Designed to further expand on the sealing performance that has been achieved with Valve Lubricant 601™. Valve Sealant 701 is a corrective maintenance solution with the capability to seal leaking gate valves where previous attempts have failed.
Valve Lubricant 701 - damaged gate valve sealant
Gate valves leak when there is damage across the sealing surfaces of the gate or seats, in the form of galling, scoring or cutting, and the severity of the damage is key to how well a certain lubricant or sealant will perform. Valve Sealant 701 and 701-L’s sealing particles help more severely damaged valves than 601. Assisting the valve to hold pressure across the seal system so that operations can continue with limited down time.
Field proven for the emergency isolation of leaking gate valves
- Able to seal gate valves which have moderate to severe damage on the gate (unlike 601) and seats.
- Proven in pressure test workshop by using purposely cut seats in the test valve.
- Performance proven in field deployment with success where previous attempts to seal the valve have failed.
- Does not harden like other sealants offering consistent, market leading sealing capabilities.
Industry recognition
Reduced operational costs
701 is guaranteed to reduce the operational costs associated with leaking valves. When planning your intervention job, where you will require integral well barriers, ensure you have Valve Sealant 701 and a suitable RS Clare spec pump system BEFORE YOU START THE JOB.
Enhanced sealing capabilities
The sealing performance of 701 is documented in Pressure Test Workshop Report and Case Study Field reports. For more information please contact us and a member of our technical team will be in touch.
Using a buried check valve?
Valve Sealant 701-L should be used in gate valves with moderate to severe leaks, where the use of Valve Sealant 701 is not possible because the specific model of gate valve has a secondary, “buried” check valve injection fitting. Valve Sealant 701-L is fully compatible with Valve Sealant 701 and Valve Lubricant 601.
