Surface-controlled subsurface safety valve KO-U
Main Features and Benefits
- Fail-safe design enables forced opening of the valve with a safety sleeve when surface control is lost;
- Complete isolation and sealing are achieved irrespectively of the reservoir pressure;
- Built-in pressure equalization system;
- With valve open, the flapper is not exposed to fluid flow;
- Valve body protects the flapper and the seat during wireline operations;
- Internally nitrided components are case-hardened, durable and corrosion-tolerant to resist fracturing fluid;
- Tool's components are plated or coated with phosphate.
Application
- Gas and gas condensate wells requiring downhole shut-in;
- Large volume fracturing.
