Available sizes: 2 3/8”, 2 7/8”, 3 1/2”, 4”, 4 1/2”, 5”, 5 1/2'” and 7”.

The 5 1/2" Surface-Controlled Subsurface Safety Valve (SCSSSV) serves a critical safety function by enabling rapid well shut-in if uncontrolled flow occurs due to equipment malfunction or damage. Positioned in the upper section of the wellbore, this valve acts as a barrier to isolate the production pathway, helping to prevent uncontrolled release of fluids and protect personnel, equipment, and the environment.

Its fail-safe design means that any loss of control pressure or system failure causes the valve to close automatically, ensuring well integrity even in emergency situations. The valve uses a wireline-retrievable flapper mechanism that is surface-controlled, allowing operators to maintain or replace key components without pulling the tubing string—significantly reducing downtime and operational costs.

Engineered for wells utilizing 5 1/2" (139.70 mm) tubing, this valve fits landing nipples with a 4.562” seal bore and supports working pressures up to 5,000 psi. The internal valve diameter of 2.38” is designed to balance flow efficiency and tool passage capability. Additionally, by positioning the sealing surfaces outside the flow path when open, the valve minimizes wear caused by erosive fluids, enhancing durability and service life.

This SCSSSV provides a reliable, maintainable solution for well control in demanding operational environments, combining robust construction with practical features to support continuous production and rapid emergency response.

Available sizes: 2 3/8”, 2 7/8”, 3 1/2”, 4”, 4 1/2”, 5”, 5 1/2'” and 7”.

The 7-inch Subsurface Controlled Surface Safety Valve (SCSSSV) is a critical safety device designed to automatically shut in a well if uncontrolled flow occurs due to equipment failure or damage. It is installed in the upper part of the well to quickly isolate the producing zone and prevent uncontrolled release of fluids, ensuring well control in emergency situations.

This valve uses a flapper mechanism and is surface-controlled, meaning it can be operated from the surface. It features a self-equalizing design that reduces pressure differences across the valve during opening and closing, which improves reliability and extends valve life. The sealing surfaces are located outside the flow path when the valve is open, reducing wear and protecting key components from erosion.

Because the valve is wireline retrievable, it can be serviced or repaired without pulling the entire tubing string, minimizing downtime and intervention costs. It fits 7-inch tubing and is available with landing nipple seal bores of 5.750", 5.875", or 5.963". It can handle working pressures up to 10,000 psi and offers valve internal diameters of 3.38" and 3.50", allowing operators to balance safety and flow requirements effectively.

The 4” Tubing End Locator is designed specifically for use with larger production tubing strings common in wells that require greater flow capacity or enhanced mechanical strength. This size is typically found in wells with higher production rates or more demanding operational requirements, where accurate depth confirmation becomes even more critical.

This model is specifically sized for 4-inch outer diameter tubing, featuring a maximum outside diameter that fits comfortably within the tubing’s internal dimensions. This sizing ensures that the locator can move smoothly without obstruction while maintaining effective contact to detect the tubing end. The core mechanism involves a spring-loaded finger that extends outward upon contacting the tubing bottom. This movement translates into a tactile signal felt at the surface, eliminating the need for complex electronic systems and reducing the risk of failure in harsh downhole environments.

Equipped with standardized threaded connections—commonly a 1-9/16 - 10 UN pin on the top and a 1 - 11 ½ NPT box on the bottom—the tool integrates easily into typical slickline, wireline, or coiled tubing toolstrings. The fully mechanical design enhances reliability, making it well-suited for use in conditions of high pressure, elevated temperatures, and corrosive fluids often found in oil and gas wells.

The 4” Tubing End Locator is especially valuable in wells with larger tubing sizes where accurate depth confirmation is critical to avoid operational errors. By providing a straightforward and dependable method to locate the tubing end, it supports safe and efficient well intervention, helping to reduce downtime and operational risks.
