WRDP-1 slickline-retrievable subsurface safety valves are designed for sweet to moderately corrosive environments and feature rod-piston operation with flapper valves and an internal equalizing system that can be disabled by plugging the equalization ports before installation.
These valves are normally supplied with a fit-for-purpose lock for convenient use as a primary valve in applications where a value-engineered slickline valve is desired.
The WRDP-1 is operated by a rod-piston, premium sealing system. The primary flapper mechanism also has full metal-to-metal sealing and a secondary soft seat.
Some models of this valve are designed to be spring-spacer adjustable (SSA). SSA valves permit closing pressures to be varied during valve assembly by substituting spacers of different lengths instead of changing the power spring.
