  • Ball Valves-Image
    Ball Valves - (2084 companies)
    Ball valves are quarter-turn, straight-through valves that have a round closure element with matching rounded seats that permit uniform sealing stress. The valve gets its name from the ball that rotates to open...

  • Solenoid Valves-Image
    Solenoid Valves - (999 companies)
    Solenoid valves are devices that use a solenoid to control valve activation. They are considered electromechanical control devices used to control liquid or gas flow. An electrical current runs through a coil to control the valve by moving a plunger...

  • Check Valves-Image
    Check Valves - (1953 companies)
    The mechanics of check valve operation are relatively simple. Most check valves contain a ball that sits freely above the seat, which has only one through-hole. The ball has a slightly larger diameter than that of the through-hole. When the pressure behind...

    Gate Valves - (1173 companies)
    Gate valves and knife valves are linear motion valves in which a flat closure element slides into the media stream to shut off flow. Gate valves (also known as knife valves or slide valves) are linear motion valves in which a flat closure element...

A major utility approached Superbolt about using their Multi-Jackbolt Tensioners to reduce down-time on their large Ball Valve. Previously they used a hydraulic bolting method. The estiamted time savings was 2-3 days with the Superbolt Tensioners, and an estimated 5 million dollars (US) was saved...

For more than four decades, Worcester Controls Corporation has been on the leading edge of ball valve and flow control technology. The Marlborough (Mass.) company has always prided itself on making and selling state-of-the-art products of the highest quality. So Worcester was seriously concerned...

The standard manual three-way valve is usually installed so that the bottom port â Câ is the common port. Turning the handle 90 degrees diverts the flow to the right, port â Aâ or to the left, port â Bâ , or turns the flow off. Thereâ s a couple of things to remember though. Letâ s say...

RuB ball valves have a unique feature which gives them substantial performance advantages over many other ball valves. The lip portion of the teflon (R) seats in all RuB ball valves is free to flex. The seats act as springs, which can absorb variations in temperature or pressure....

More and more attention worldwide is being focused on fugitive emissions. Fugitive emissions are defined variously and may refer to a wide range of emissions not confined to a stack, duct, or vent, including emissions from bulk handling or processing of raw materials, windblown dust, and other...

One of the key advantages of a ball valve over older types (such as conical plug valves, which are the traditional valve used for gas meter sets) is that the ball valve seals absolutely bubble-tight without any sealant or lubricant being required. The reason for this is that the geometry of a ball...

RuB ball valve styles which use teflon stem seals (s.40, 42, 70, and 92) are rated at 150 psi WSP (Working Steam Pressure). But our valve styles which have FPM (like DuPont Viton (R)) stem seals (the s64 or s95 for example) cannot be consistently satisfactory at 150 WSP without some restrictions...
