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.
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.

Abstract: A control system for decreasing pressure of a supercritical water system and a method therefor is provided, mainly including: a resistance water storage tank, a resistance pump, a capillary negative booster, a back pressure valve, a regulating valve and related stop valves. By switching the back pressure valve branch and the capillary negative booster branch, the pressure regulation is achieved while starting the system, closing down and in normal operation. The present invention is capable of achieving precisely controlling pressure of the system on the basis of effectively preventing problems exists in the solid particle materials pressure decreasing process such as abrasion and clogging of the internal elements of the valve. In addition, the back pressure valve branch is capable of reducing the operation complexity in the starting and shutdown process of the system, and the operation reliability is improved.

A first flowpath includes an inner bore of the annular valve seat. A second flowpath includes an aperture formed between the annular valve seat and the tubular duct. The poppet valve is configured to engage the annular valve seat and substantially close the first flowpath when the poppet valve is in a first position. The poppet valve is further configured to disengage the annular valve seat and at least partially open the first flowpath when the poppet valve is in a second position.

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.
