PacSeal Hydraulics offers various accessories to all SV directional control valves to improve the value and efficiency of a hydraulic control system. The SV pin lock detent kit can easily be mounted to a valve to increase safety and prevent accidental shifting. Bracket mounted actuators are easy to assemble to an existing SV valve to create remote operation. To enhance the user interface and have visual knowledge of a valve’s position, simply fasten a nameplate with the valve’s existing hardware.

PacSeal understands that nothing lasts forever, which is why we provide OEM repair kits and maintenance instructions for all of our directional control valves.

SV Valve Accessories

SV Pin Lock Detent Kits

PacSeal Hydraulics’ patent-pending SV pin lock detent kit is the best solution for preventing accidental valve shifting and ensuring two-handed operation. To shift the valve, the operator must use their other hand to pull the spring-loaded plunger up, then release it when in the new position.

Replacing the existing manual operator parts with the pin lock detent kit requires only a small adjustable wrench. See the SV with Pin Lock Detent Kit page of the respective Valve Specifications document for installation instructions.

Bracket Mounted Actuators

PacSeal’s hydraulic and OEM pneumatic cylinder actuators are the ideal products for converting the operation of SV directional control valves from manual to remote with easy-to-assemble bracket kits. The cylinder actuators can be ordered individually, with a bracket kit or assembled to the valve. Please visit our Bracket Mounted Actuators page for more information.


Adding a nameplate to an SV valve is the best way to know the valve’s position when in the field. Fastening to a valve is simple: Just remove the two bolts on the pressure side of the valve, place the nameplate atop the valve and then reinsert the bolts through the nameplate and the valve.

Nameplates may be ordered separately or fastened to the valve/actuator assembly. To order the nameplate preassembled to a valve, please visit the SV Directional Control Valve page and use the model configurator to select the nameplate add-on with the applicable code.

Ideal for general use, blank nameplates show whether the valve is in the open or close position. Available for SV-50, SV-100 and SV-150 Valves.

SV Blank Nameplates (Code – 0) Valve Size Part Number
SV-50 40-2250
SV-100 40-0694

Other nameplate options for the SV-100 valves display the valve’s open and close positions and function (e.g. pipe ram, shear ram, choke line, etc.).
