 new patent  Axial-seal butterfly valve

A valve includes a valve body having a fluid flow path extending therethrough, a valve seat located in the valve body, and a valve disc located in the fluid flow path of the valve body. The disc is rotatable between a fully open position and an intermediate position about an axis substantially perpendicular to a longitudinal axis of the disc. ... Flowserve Management Company

Power generation for valve actuators

The present invention utilizes operation of a valve actuator to generate electrical power. A portion of the mechanical energy generated by operation of a valve actuator is converted to electrical energy. ... Flowserve Management Company

Decoking control valve using dynamic rod seal

The decoking control valve includes a piston, a cylinder, and a hydraulic rod seal at the outlet ports. The piston can move translational inside the cylinder along a fixed direction. ... Flowserve Management Company

Methods related to valve actuators having motors with peek-insulated windings

A method of operating a nuclear reactor includes operating a valve actuator to open and close a valve in fluid communication with a nuclear reactor fluid control system. The valve actuator includes a motor having windings of magnet wire. ... Flowserve Management Company

Fluid flow control devices and systems, and methods of flowing fluids therethrough

Fluid flow control devices comprise a body including a central aperture extending along a longitudinal axis therethrough and a plurality of channels extending from an outer sidewall of the body to an inner sidewall of the body. At least one first channel may intersect at least one other channel. ... Flowserve Management Company

Dry running end face mechanical seal

A dry running mechanical seal is able to form a direct contact seal for extended periods at both low and high rotational speeds without undue heating or wear of the seal faces. A rear surface of the stator face and corresponding surface of a mounting plate are both lapped for maximum direct contact transfer of heat. ... Flowserve Management Company

Bearing isolator seal with enhanced rotor drive coupling

A bearing isolator seal provides enhanced coupling and stability of the rotor to the shaft, without undue seal enlargement, by including a plurality of drive o-rings in a common retention groove. In embodiments, the isolator seal accommodates axial rotor misalignment up to a maximum permitted axial misalignment, which can be at least 0.025″. ... Flowserve Management Company

Bearing isolator seal with tapered static shutoff o-ring interface

A bearing isolator seal having a shut off o-ring is tolerant of axial rotor-stator misalignment and provides an enhanced static seal while minimizing rotational wear. A tapered section of the stator is overlapped by the shut off o-ring. ... Flowserve Management Company

Sensors for valve systems, valve systems including sensors and related methods

Valve systems include at least one component comprising a conductive material and at least one inductance-to-digital converter (ldc) configured to wirelessly sense a position of at least a portion of the conductive material. The valve system is configured to determine at least one force applied to a portion of the valve system based at least partially on the position of the at least a portion of the conductive material. ... Flowserve Management Company

Sensors for valve systems and related assemblies, systems and methods

Valve systems include at least one component comprising a conductive material and at least one inductance-to-digital converter (ldc) sensor configured to wirelessly sense at least one property of the conductive material and relay a value associated with the at least one property to a control system of the valve system. Methods of sensing a position of a component of a valve system include wirelessly sensing at least one property of a conductive material of the component of the valve system with at least one inductance-to-digital converter (ldc) sensor.. ... Flowserve Management Company

Non-metallic belt-driven crosshead drive system for hydraulic decoking

An apparatus for raising and lowering a cutting tool within a decoking drum, a decoking system and a method of raising and lowering a decoking system cutting tool. Instead of using metallic ropes, chains, or a self-propelled gear-based approach, non-metallic belts are secured at respective ends to a crosshead and one or more counterweights to enable vertical movement of the crosshead that in turn permits vertical movement of the cutting tool throughout the height of the drum. ... Flowserve Management Company

Variable-speed actuator

A valve actuator including an electric motor is disclosed that includes a solid-state motor controller capable of operating a motor at variable speeds and a gear set that provides inherent braking. The speed and torque of the valve actuator may be selected. ... Flowserve Management Company

Reverse pressure capable mechanical seal

A mechanical seal designed for gas applications minimizes leakage even when the pressure differential changes direction, such as during rapid deceleration of a turbocharger. The seal faces include both inner (id) and outer (od) diameter recessed features configured to admit gas between the faces from the inner and outer face diameters respectively. ... Flowserve Management Company

Centrifugal pump impellor with novel balancing holes that improve pump efficiency

A centrifugal pump impellor includes balancing holes that reduce axial thrust while minimizing the loss of pump efficiency. In one general aspect, the balancing holes penetrate the rear shroud between the blades, and are angled in both axial and rotational directions so as to direct the leakage fluid approximately parallel to the primary process fluid, so that it causes minimal interference with the primary fluid flow. ...
