Claims

[Scope of utility model registration request]

In the guide of a pole valve for a reciprocating pump that has three or more single guides that restrict the movement of the hole valve provided on the suction side and the discharge side in a direction perpendicular to the fluid flow direction, A guide for a pole valve for a reciprocating pump, characterized in that a surface of each of the single guides on the side that contacts the pole valve, which intersects with a perpendicular surface, has an arc shape that projects toward the ball valve.
