Sharpe Valves
Stainless and carbon steel ball valves, three-piece and flanged.
Sharpe is a valve brand now sold by ASC Engineered Solutions. The line is built around stainless and carbon steel ball valves in three-piece and flanged bodies, with fire-safe and cryogenic versions of most bodies, plus a supporting range of gate, globe, check and resilient seated butterfly valves and factory-assembled actuation. ASC positions Sharpe as a stocked, distribution-served brand -- the selling point is availability and configuration out of regional delivery centers rather than heavy custom engineering.
What we carry, by measurement
Pick what you’re measuring.
The heart of the Sharpe line. All of these unbolt in the middle so the trim can be serviced without cutting the valve out. The series numbers tell you the story: a bare number is the base valve, an FS prefix adds fire testing, and FSC adds cryogenic capability.
Series 80, standard port, Class 800 and 300, API 608
The base three-piece ball valve, standard port, built to API 608.
Use it whenUse it as the everyday three-piece valve for general process isolation where you want in-line serviceability and neither fire testing nor a full port is specified.
Series 84, standard port, fire-tested, Class 600 and 300
The Series 80 body with fire-tested construction.
Use it whenUse it when the piping spec calls for a fire-safe valve on hydrocarbon service. If you are in a refinery or terminal, this is usually the version the spec wants, not the plain Series 80.
Series FSC89, full port, fire-safe and cryogenic, Class 600 and 300
A three-piece ball valve that is both fire-safe and cryogenic rated, in full port.
Use it whenUse it on cold hydrocarbon and liquefied gas service where the spec demands both fire safety and low-temperature capability -- LNG, ethylene, cryogenic transfer. ASC also lists an FSC80 as the standard-port version of the same design, so pick full port only if flow area matters.
Series 86, tube full port, instrumentation, Class 600 and 300, ASME BPE
A small three-piece instrumentation ball valve on tube connections, built to ASME BPE.
Use it whenUse it on instrument and small-bore tubing runs where the connection is tube rather than pipe and you need a serviceable valve that will not restrict the line.
Series 88, tube full port, Class 600 and 300, ASME BPE
A tube-end full-port three-piece ball valve built to ASME BPE.
Use it whenUse it on sanitary and clean-service tubing where full unrestricted bore matters and the piping is tube, not pipe.
Series 66, high purity tube, three-piece
A high-purity three-piece ball valve with a 316L stainless body and tube full port, in-line serviceable by swinging the center section out without disturbing tubing alignment. ASC's datasheet describes a floating ball with a relief hole to prevent cavity pressure buildup and a live-loaded, bottom-entry, blowout-proof stem.
Use it whenUse it where cleanability and purity drive the spec -- pharmaceutical, biotech, high-purity chemical -- and where you need to service the valve without breaking tubing alignment. This is the closest thing in the Sharpe line to what our current copy calls a high-purity valve.
Series V84, V-ball three-piece control ball valve
A three-piece body with a V-notched ball for throttling.
Use it whenUse it when you need modulating control from a three-piece rotary valve and want to keep the in-line serviceability. Specify the positioner with it.
Series D88, tube full port diverter, Class 600 and 300
A three-way three-piece diverter ball valve on tube ends.
Use it whenUse it to route one stream between two destinations on clean tube piping instead of building it from two valves and a tee.
The same fire-safe and cryogenic naming logic applied to flanged bodies, in standard and full port.
Series 54, standard port, flanged, Class 150
The base flanged ball valve, standard port, ASME Class 150.
Use it whenUse it where the line spec is flanged Class 150 and you need straightforward isolation. Standard port keeps cost and weight down where a small pressure drop is acceptable.
Series FS54, standard port, fire-tested, flanged, Class 150 and 300
The Series 54 with fire-tested construction, extended to Class 300.
Use it whenUse it when the spec calls for a fire-safe flanged valve. Same selection logic as the 84 versus 80 on the three-piece side.
Series FS50, full port, fire-tested, flanged, Class 150, 300 and 600
A fire-tested full-port flanged ball valve across three classes.
Use it whenUse it when you need both fire testing and an unrestricted bore -- pump suction, gravity lines, anywhere pressure drop matters and the valve still has to be fire-safe.
Series FSC70, full port, fire-safe and cryogenic, flanged, Class 150 and 300
A flanged full-port valve that is both fire-safe and cryogenic rated.
Use it whenUse it on cold flanged service where both requirements apply.
Series FSC74, standard port, fire-safe and cryogenic, flanged, Class 150 and 300
The standard-port version of the FSC70.
Use it whenUse it in place of the FSC70 when you do not need full bore and want the lighter, less expensive body.
Series D54, standard port, flanged diverter, Class 150
A flanged three-way diverter ball valve.
Use it whenUse it to split or combine flow on flanged Class 150 piping with one body and one actuator.
The rest of the Sharpe catalog, filling out a piping package alongside the ball valves. ASC describes these at the category level rather than publishing a series list on the brand page.
Gate, globe and check valves
Conventional linear valves in the Sharpe range.
Use it whenUse gate valves for straight-through isolation, globe valves where throttling and tight shutoff on a smaller line matter, and check valves to block reverse flow. Practical reason to buy these from Sharpe is packaging them on one order with the ball valves.
Resilient seated butterfly valves
Elastomer-seated butterfly valves for larger-line isolation.
Use it whenUse it at 3 inch and up on clean, low-pressure service -- water, cooling, general utility -- where a ball valve is heavier and dearer than the job justifies.
ASC assembles and customizes Sharpe valve packages rather than selling only bare valves.
Control valve packages
Sharpe valves supplied as assembled and configured control packages.
Use it whenUse it when you would rather receive a valve, actuator, positioner and accessories as one tested assembly than source and assemble the pieces. ASC states it customizes valve assemblies to customer specification.
Actuators and accessories
Pneumatic and electric actuation plus the accessory hardware, mounted to Sharpe valves.
Use it whenUse it when automating a Sharpe valve, so mounting, torque and position feedback are the supplier's responsibility rather than yours.
