An oil passage portion forms a part of an oil supply passage inside. A check valve part includes a valve seat portion press-fitted into the oil passage portion. The check valve part allows flow of hydraulic oil from a hydraulic oil supply source to a hydraulic chamber, and restricts flow of the hydraulic oil from the hydraulic chamber to the hydraulic oil supply source. A filter is provided downstream of the valve seat portion in the oil supply passage so as to collect a foreign matter in the oil supply passage.

A valve including a body having an inner central orifice and a chamber, a piston formed by a rod and by a head mounted in the chamber, the rod extending outside the body and moving in a bore of an application system. The valve includes a first sealing device around the rod on one side of the valve where the rod extends outside the body, part of the chamber being filled with a pressurized control fluid to obtain movement of the piston against the force of a spring housed in the body. The valve includes a second sealing device around the rod, between the first sealing device and the chamber. The valve includes a vent duct in the rod that communicates with the inner central orifice between the first and second sealing devices and emerges in the open air or in part of the chamber communicating with the open air.

A leak proof, completely sealed solenoid valve, comprising a housing 14 having a fluid flow path controlled via an electrically operated mechanism to control a flow; the mechanism comprises metallic coil 20 coiled around a bobbin 16 supported by a magnetic bracket 24 with terminal pins 18 connected to the bobbin 16 for receiving electrical input to facilitate an energized and de-energized state to control the movement of a poppet 34 shaft that obstructs the flow; wherein, the bobbin 16 comprises micro-melting fins, thereby housing over molding creates strong bond between two materials; a permanent weld is created between the bobbin 16 and the housing 14 to prevent internal leakage; and the completely sealed solenoid valve limits emissions and evaporations of the volatile fuel components into and from the valve, and contribute to reliability and robustness of the product by completely sealing the nozzle and housing using laser welding.

Valve for a system for applying a covering product, including projecting or recessed shapes on a peripheral part, configured to cooperate with projecting or recessed shapes of a dedicated mounting and dismounting tool, these projecting or recessed shapes of the valve being configured to transmit a rotational movement to the valve, and to be secured to the tool. The projecting or hollow shapes of the valve include a first peripheral profile having at least one planar surface, and a second peripheral profile located behind the first profile relative to an outer end of the valve. The second profile has at least one first planar surface aligned with the planar surface of the first profile, and at least one second planar surface angularly offset relative to the planar surface of the first profile, such that the second planar surface of the second profile forms a shoulder relative to the first profile.

There is provided an irrigation valve with embedded rings for reinforcement of valve ports. The valve has a valve body and threaded flow paths, the flow paths including an outlet and an inlet on opposite sides of the valve body. Irrigation piping is attached to the inlet and to the outlet. The reinforcement rings at the inlet and the outlet prevent fracturing of the valve body and/or piping due to overtightening of the piping. Further provided is a scrubber for an irrigation valve. The scrubber and frees debris on a filter. The scrubber may be manually extracted for maintenance or replacement without the need for mechanical tools.

A method of servicing a trim cartridge assembly for a valve assembly. The method includes cutting a portion of a bonnet of a trim cartridge assembly and separating the bonnet from a cage of the trim cartridge assembly. The method also includes removing at least one of a retaining ring, a remaining portion of the bonnet, and a spiral wound gasket. The method still further includes replacing the remaining portion of the bonnet with a spacer of a trim cartridge repair kit and disposing a replacement flat sheet gasket of the trim cartridge repair kit at a first end of the spacer. The method also includes disposing a replacement spiral wound gasket of the trim cartridge repair kit at a second end of the spacer opposite the first end of the spacer.
