A perimeter seated knife gate valve is described. Perimeter and transverse seals may be formed together as a single-piece or as two separate pieces. Wire-reinforced and with a rectangular cross section, the perimeter seal (portion) may fit into a corresponding groove in the single-piece body of the valve. Transverse seal (portion) may include two channels formed as side grooves or tubular channels to accept packing material, which energize the seal and are isolated from the fluid stream. In the two-piece version, a bottom groove of the transverse seal may be used to interlock both pieces. The shape and structure of the seal may allow single-piece valve body.

A diaphragm valve has a valve body with a passage to be opened to allow fluid to pass through the valve body and to be closed to prevent fluid from passing through the valve body, and has a bonnet assembly with a pressure ring to load and unload a diaphragm based on a first spring constant to seal a peripheral portion of the diaphragm, and a compressor to close or open the passage of the valve body. The valve body and bonnet assembly have a connection that allows the valve body and bonnet assembly to be substantially fixed together with a second spring constant that is substantially higher than and independent from the first spring constant.

Temperature compensating flanged joint for a teflon diaphragm valve
Apparatus, including a diaphragm valve, is provided featuring a valve body, a diaphragm, a pressure ring, and at least one elastomeric member. The valve body may include a circumferential flange. The diaphragm may include a circumferential gasket portion configured to be seated on the circumferential flange so as to form a joint between the valve body and the diaphragm.

Knife gate valve with multi-piece elastomer liner and/or o-rings at flange interface
A knife gate valve comprising a two-piece valve body, a knife gate, an elastomeric transverse seal, an elastomeric perimeter seal, and a pair of elastomer liners. Each elastomer liner is positioned between the knife gate and one of the mating valve body halves and defines a chamber for receiving the perimeter seal. Each liner has a port that corresponds to the flow channel, a sealing portion that extends into a sealing chamber to cooperate with the transverse seal, and an orifice liner extension that lines the orifice of the corresponding valve body half. O-rings, preferably of a softer material than the elastomer liner, may be positioned on the outer rim of the orifice liner extensions for creating a seal among the elastomer liner, the corresponding valve body half, and a corresponding mating flange of a fluid handling system.

A quarter-turn valve includes a valve body having an inlet, an outlet, and a diaphragm adjacent arranged in said valve body for movement between a closed and opened position for restricting and controlling fluid flow. The valve further includes an input shaft for receiving a torsional input load in a closing direction and a torsional input load in an opposite opening direction. A cam is mounted on the input shaft. The cam transforms input loads to linear output loads that flex the diaphragm between its closed and opened positions.
