  • Patent number: 10544868
    Abstract: Embodiments of the invention provide a trim arrangement for a ball valve. The trim arrangement includes a first seat assembly having a first seat, a threaded collar, and a biasing element. The first seat is in contact with a first side of a ball element, and the threaded collar is threadably coupled to the first seat and in engagement with the biasing element. The trim arrangement further includes a second seat assembly having a second seat in contact with a second side of the ball element. The biasing element biases the first seat toward the first side of the ball element to provide a contact stress between the first seat and the first side of the ball element and the second seat and the second side of the ball element. The contact stress provided by the biasing element is adjustable by rotating the first seat.

  • Patent number: 10539132
    Abstract: Insert elements that may be positioned within a high pressure plug valve. The elements have two or more recessed grooves formed around the fluid opening of the elements. The grooves are spaced from one another. A seal is placed in one and only one of the grooves. As wear occurs, the seal is relocated to one of the other grooves. Instead of a series of spaced grooves in a single insert element, a kit may be formed from two or more otherwise identical insert elements, each with a single recessed groove at a different position around the fluid opening.

  • Patent number: 10502329
    Abstract: A valve having an inlet, exhaust, control port, and diaphragm. The diaphragm moves between an open position, in which the inlet and exhaust are in fluid communication, and a closed position, in which the diaphragm blocks fluid from flowing between the inlet and the exhaust. The diaphragm moves from the closed position to the open position when an inlet force due to pressure at the inlet is greater than the sum of the biasing force and a control port force due to pressure at the control port. The valve is operable to automatically drain contaminants from a vehicle air reservoir when the vehicle's emergency brakes are set. To reduce noise, the diaphragm of the valve is preferably in tension when in the closed position, and/or the diaphragm opens a limited distance when in the open position so that a back pressure is generated at the inlet.
