Ball Valves with trunnions help maintain consistent flow rates for high capacity, heavy-duty applica- tions. They have a rotatable ball with a cylindrical flow passage through the center to the con- trol flow. When the ball is turned one-quarter of the way, the flow stops. The port of a full-port or full- bore ball valve equals the pipeline diameter and presents little or no restriction to flow to allow for pig- ging when not attenuated.
Eccentric Plug Valves combine globe valve ruggedness with the efficiency of a rotary valve so they’re also referred to as rotary globe. They have a plug-shaped,- flow-restricting member that follows an eccentric path as it rotates.
Globe Valves use a linear motion to move a closure member into and out of a seating surface. They have a body distinguished by a globular-shaped cavity around the port region. Many single-seated valve bodies use cage or retainer-style constructions to re- tain the seat ring, provide valve plug guiding, and provide a means for es- tablishing particular valve flow char- acteristics.
High-Performance Butterfly Valves are used in throttling ap- plications requiring large flow capacities and small installed footprints. They use a rotating eccentric disk to control flow through a pipe. The disk is generally operable through 90 de- grees and provides a linear flow characteristic. These valves have nominal sizes from DN50 to DN1800 (from NPS 2 to 72) and pressure class up to PN420 (CL2500 according to ASME) depending on the model.
The MR95 Series is a versatile, compact, high-capacity di- rect-operated regulator capable of solving the toughest pressure control applications. Possible applications include oxygen systems, inert gas systems and corrosive gas service. The regu- lator is available with cryogenic materials, differential pressure control, high temperature and high-pressure optional con- structions.
Segmented Ball Valves provide high capacity, precise control across a broad range of appli- cations. They are similar to a conventional ball valve, but with a contoured V-notch segment in the ball. This control valve has good rangeability, control, and shutoff capability. The V-notch ball provides positive shearing action and produces an inherent equal percentage flow character- istic.
Severe Service Ball Valves have a simplistic, two-piece floating ball design with integral met- al seat meant to provide tight shutoff in high temperature, high pressure, and erosive appli- cations across all industries.
Three-Way Valves are a type of globe valve that have three pipeline connections to provide converging (flow-mixing) or di- verging (flow-splitting) service. Variations include cage-, port-, and stem-guided designs, selec- tions for high-temperature ser- vice, and end connections can be specified to mate with most piping schemes.
The Type 1098 regulators are capable of providing accurate, fast response and high-ca- pacities in low-pressure drop systems. Typical applications include: inert gas and plant air headers.
The Type 63EG-98HM is a com- pact, fast response, high accu- racy relief valve/backpressure which is suitable for gas or liq- uid service. The valve’s design makes it ideal for pump recir- culation especially in skid pack- ages where space is limited. Available constructions include units suitable for sea water ap- plications.
