Safety Valves

Subsurface safety you can trust. Weatherford’s Optimax™ series subsurface safety valves provide positive shutoff protection in case of catastrophic loss of well control. With more than 1,200 years of cumulative in-well valve life, the Optimax series of valves have demonstrated industry-leading reliability.

The Optimax series provides reliable service for a vast majority of well conditions, with pressure ratings of 5,000, 10,000 and 15,000 psi (34, 69 and 103 MPa); sizes ranging from 2 3/8- to 7-in. tubing; and a 350°F (177°C) temperature rating. Whether surface or subsurface controlled, our valves are certified to API 14A, Q1 ASME SPPE 1 specifications and offered in various classes of service.

Effective solutions for expensive problems. The Renaissance™ system of safety valves provides unique, cost-effective solutions for common well problems that previously required expensive repair. The Optimax WDB is the ideal safety valve for damaged sealbores. The Optimax WDCL works on damaged and broken control lines or will retrofit wells without safety valves. And the Optimax Opti-Chem™ WCS offers a retrofit solution that provides a capillary-injection system and a surface-controlled safety valve—without a workover
