Abstract: A method of controlling an actuator includes switching a primary solenoid valve to a first mode to fluidically connect a supply pressure source to a control chamber of a pilot valve. A fluid from the supply pressure source is directed through the primary solenoid valve to fill the control chamber of the pilot valve and put the pilot valve in a first position. The first position fluidically connects a second chamber of the actuator to a return pressure source. The actuator includes a cylinder between the first chamber and the second chamber and a rod attached to the cylinder. The fluid from the supply pressure source is directed into the first chamber of the actuator to move the cylinder and the rod in a first direction while the pilot valve is in the first position.

Abstract: A multi-port valve for a water treatment system includes a housing having an inlet port, an outlet port, a drain port, a first resin port, a second resin port resin, and a cavity fluidically coupling each of the ports. A drivetrain subassembly is coupled to the housing and includes a first motor and a leadscrew. An injector subassembly is coupled to the housing and includes a second motor, a brine port, and a brine valve. Further, a piston is disposed on the leadscrew and configured to laterally traverse a length of the leadscrew in response to rotation of the leadscrew.

Abstract: An example valve includes: a plurality of ports comprising: a first port, a second port, and a third port; a spool configured to block fluid flow from the first port to the third port while allowing fluid flow from the third port to the second port when the valve is in an unactuated state; a spring applying a biasing force on the spool in a proximal direction, wherein when the valve is actuated, the spool moves in a distal direction against the spring, thereby allowing fluid flow from the first port to the third port while blocking fluid flow from the third port to the second port; and a turbine configured to rotate as fluid flows from the first port to the third port when the valve is in an actuated state.

Abstract: A guide frame for a four-way reversing valve includes a frame body. Both ends of the frame body include a connecting portion, respectively. The connecting portion includes a first bending member and a second bending member, and the directions of bending of the first bending member and of the second bending member are opposite. The connecting portion includes a reinforcing member. The reinforcing member includes a first reinforcing plate and a second reinforcing plate. The first reinforcing plate is connected to the inner side of the first bending member by welding and the second reinforcing plate is connected to the inner side of the second bending member by welding. The connection strength of the connecting portion is increased, such that the guide frame is less likely to deform or break.
