A fluid manifold can be produced with additive manufacturing. The manifolds can tolerate a range of temperatures, pressures, and/or fluid flow speeds, and are compatible with a variety of fluids and/or gases. The fluid manifold can receive an insertable or installable valve, such as a cartridge valve.

A cartridge check valve includes a body and removeable cartridge. The check valve protects itself from failure by forming an oil barrier between hot gas and debris and the sealing components. If sealing areas in the cartridge check valve fail, the cartridge can be removed and replaced with another replaceable cartridge. The body of the check valve typically does not need to be replaced, thereby reducing carbon footprint. A preferred cartridge includes two balls, each ball sealing against a seating surface to form two seals within the cartridge.

An insertion valve comprises a first casing comprising a trunk bore defining a diameter, a second casing opposite the first casing, and a boss within the first casing and extending beyond the diameter of the trunk bore. In various aspects, the insertion valve can comprise a casing comprising a sleeve surrounding a trunk bore and a monolithic bridge directly coupled to the sleeve. Interlocking gasket can further comprise an annular seal component comprising a first notch diametrically opposed from a second notch and a wedge seal component comprising a first head coupled to the first notch and a second head coupled to the second notch.

A fluid pump may include a power end, a fluid end having a cartridge bore, and a valve cartridge configured for insertion into, and removal from, the cartridge bore as a unit. The valve cartridge may include a cartridge body having a fluid inlet and a fluid outlet, a first valve assembly configured to control fluid flow through the fluid inlet, and a second valve assembly configured to control fluid flow through the fluid outlet.

The present disclosure provides an electric valve, including: a valve seat, the valve seat having an end surface and a slot; a valve body, a portion of the valve body penetrating in the valve seat, and another portion of the valve body protruding from the end surface; a coil portion sleeved over the valve body, the coil portion and the slot being respectively located on two sides of the end surface; and a connection portion, the connection portion including a connection member and a support member and a clamping member arranged on the connection member. The connection member is fixedly connected to the coil portion, the support member abuts against the end surface, and the clamping member is clamped with the slot.

One or more check valves may be used in a motor protector for an ESP assembly. Disclosed embodiments relate to a check valve adapter configured to provide additional versatility regarding such check valves. The adapter may have a first end portion, configured for removable attachment to an NPT screw-style vent port, and a second end portion configured to receive a cartridge-style check valve. The first end portion of the adapter is in fluid communication with the second end portion, and the second end portion can be configured to receive the cartridge-style check valve in either orientation, thereby allowing fluid flow through the adapter in either direction merely based on the orientation of the cartridge-style check valve. Systems for using an adapter with a cartridge-style check valve in an ESP assembly, as well as methods of controlling fluid flow in a motor protector using such an adapter, are also disclosed.

A pressure relief valve that is spring-activated or utilizes a burst disk is described for preventing pipe bursts in a building plumbing system. A control valve system and method for preventing pipe bursts utilizing the pressure relief valve are also described. Also described are spring-activated control valve cartridges and control valve systems utilizing spring-activated control valve cartridges that prevent pipe bursts when installed building plumbing systems. Further described are methods for preventing pipe bursts in building plumbing systems comprising the step of disposing a relief valve or spring-activated cartridge according to the disclosure in a building plumbing system.

Multi-port valve for controlling a medium in a refrigerant circuit of a refrigeration system. A stroke movement of the valve body along an axis is controllable by an actuating element of a drive. The valve body is tubular and extends along the stroke axis and, in a first end position of the stroke movement, passes through at least one first pressure chamber between an inlet and an outlet and at least one further pressure chamber between the inlet and at least one further outlet. At least one seal is associated with each pressure chamber for abutment against the valve body.
