Introduction
Scope of Manual
This instruction manual provides installation, operation, maintenance, and parts information for the Fisher Vee‐Ball
SS-84PSV4 NPS 4x3 and NPS 5x3 rotary control valve (see figure 1). It also outlines the assembly and testing
procedures for the NPS 4x3 CL2155 and NPS 5x3 CL2075
SS-84PSV4 rotary ball valve designed for use with the
1052PSV size 60 rotary actuator.
The SS-84PSV4 valve is the pressurizer spray valve for use in third generation PWR Nuclear Generating Stations. The
NPS 4x3 valve body has NPS 4 buttweld ends and the NPS 5x3 valve body has NPS 5 buttweld ends. Both valves have
3-inch Fisher Vee-Ball internal trim, which operates against a spring-loaded sleeve seal.
This valve contains several enhanced features compared to the original SS-84 designs which operated in previous PWR
Reactors. These features include the following:
D
Vee­Ball, drive shaft, and actuator lever connections are a missing tooth spline design ensuring One-Way only
assembly.
D
Side body flange allows trim removal without actuator removal.
