1. A control valve, comprising:
- a body having a longitudinal bore that defines a first aperture at a first end of the body and a second aperture at a second end of the body, opposite the first end of the body, and a radial third aperture in fluid communication with the bore of the body;
a first end cap having a longitudinal bore defining a first port of the control valve, the first end cap positioned adjacent the first end of the body, extending into the bore of the body through the first aperture, and removably secured to the body;
a second end cap having a longitudinal bore defining a second port of the control valve, the second end cap positioned adjacent the second end of the body, extending into the bore of the body through the second aperture, and removably secured to the body;
an insert having a bore defining a third port of the control valve, the insert positioned adjacent the third aperture and removably secured to the body; and
a piston positioned within the bore of the body and movable between a first position in which the first port is in fluid communication with the second port and not with the third port and a second position in which the first port is in fluid communication with the third port and not with the second port.

Abstract
A control valve includes a body, a first end cap, a second end cap, an insert, and a piston. The first end cap, second end cap, and insert are removably secured to the body and define a first port, second port, and third port of the control valve, respectively. The piston is positioned within the bore of the body and is movable between a first position in which the first port is in fluid communication with the second port and not with the third port and a second position in which the first port is in fluid communication with the third port and not with the second port.

14. A control valve, comprising:
-
a body having a longitudinal bore that defines a first aperture at a first end of the body and a second aperture at a second end of the body, opposite the first end of the body, and a radial third aperture in fluid communication with the bore of the body; a first end cap having a longitudinal bore defining a first port of the control valve, the first end cap positioned adjacent the first end of the body and extending into the bore of the body through the first aperture; a second end cap having a longitudinal bore defining a second port of the control valve, the second end cap positioned adjacent the second end of the body and extending into the bore of the body through the second aperture; a piston positioned within the bore of the body and movable between a first position in which the first port is in fluid communication with the third aperture and not with the third port and a second position in which the first port is in fluid communication with the third port and not with the third aperture; a first valve seat secured to the first end cap such that the first valve seat can move radially to allow the first valve seat to align and seal with a second sealing surface of the piston when the piston moves into the second position; and a second valve seat secured to the second end cap such that the second valve seat can move radially to allow the second valve seat to align and seal with a first sealing surface of the piston when the piston moves into the first position. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
