Swagelok 40 Series Ball Valve
Overview
Swagelok 40 Series Ball Valve is a one-piece instrumentation ball valve engineered for demanding on-off, switching, and crossover flow duties across process and instrumentation systems. With nearly four decades of proven field service behind its design, the Swagelok 40 Series Ball Valve combines a compact one-piece body with a quarter-turn ball mechanism, delivering reliable shutoff at working pressures up to 3000 psig (206 bar) across a wide range of end connections and flow path configurations.
With engineering support in Muscat, Seven Star LLC supplies the Swagelok 40 Series Ball Valve to industrial, oil and gas, and process customers across Oman and the wider GCC. Seven Star LLC supplies Swagelok 40 Series Ball Valves on request with manufacturer documentation and local technical support – serving facility engineers and procurement teams in Muscat, Sohar, and Salalah.
Working Principle
The Swagelok 40 Series Ball Valve operates on the quarter-turn ball valve principle: a precision-machined ball with a bored flow passage rotates ninety degrees between fully open and fully closed positions, providing rapid, positive shutoff with minimal actuation force. In the open position, the bore aligns with the flow path for essentially unrestricted flow, while a ninety-degree rotation of the handle seats the ball against its seals to stop flow completely, giving operators unambiguous visual confirmation of valve status from handle position alone.
The one-piece body construction of the 40 Series eliminates the potential leak paths associated with multi-piece valve bodies, while its design permits packing adjustment while the valve remains inline, avoiding the need to isolate and remove the valve for routine maintenance. This combination of a simple, robust mechanism and serviceable packing makes the 40 Series a dependable choice for both simple on-off shutoff duty and more complex switching or crossover flow arrangements within instrumentation and process piping.
Engineering Design of the Swagelok 40 Series Ball Valve
The Swagelok 40 Series Ball Valve is available in stainless steel, brass, and Alloy 400 body materials, with end connections ranging from 1/16 to 3/4 in. and 3 to 12 mm to match Swagelok tube fitting, pipe thread, or other process connection standards. The valve is rated across a temperature range of -65°F to 300°F (-53°C to 148°C), supporting both ambient environmental installations and heated-process applications within a single valve platform.
Beyond the standard two-way straight and angle patterns, the 40 Series is offered in three-way switching, four-way crossover, and five-way switching configurations, giving system designers flexibility to consolidate multiple flow-direction functions into a single valve body. A range of actuator options, including pneumatic and electric actuators compliant with ISO 5211 mounting, allows the 40 Series to be automated for remote or process-control operation, while manual lever and directional handle options remain available for straightforward field use.
Key Features

The items on this page cover the small-bore components an instrument technician handles most often. Swagelok tube fittings join metric and fractional tubing without threading or welding. Swagelok ball valves are represented by the 40 series, the 40G series one-piece instrumentation ball valve (for example SS-43GS4) and the three-way pattern listed as 40GX. The SS-1RS4 is an integral bonnet needle valve from the 1 series. VCR metal gasket face seal fittings serve high-purity and vacuum lines, QC series quick-connects are used where lines are coupled and uncoupled often, and the KPR series is a pressure-reducing regulator.Where Swagelok components are used
Typical duties are transmitter hook-ups, manifolds and impulse tubing, analyzer shelters and sample conditioning panels, chemical injection skids, gas cylinder panels in laboratories, and test benches. In oil and gas service across the GCC, the usual questions are material grade, pressure rating at temperature and, for sour service, whether the manufacturer offers the item to NACE MR0175 requirements.Ordering Swagelok fittings and valves: what we need
A Swagelok ordering number carries most of the specification. In SS-43GS4, SS is 316 stainless steel, 43G identifies the valve series and size, and S4 is a 1/4 in. Swagelok tube fitting end connection. Send the complete ordering number including any suffix for handle, seat or cleaning option. If you do not have it, give us the tube outside diameter and wall thickness, body material, end connections on each port, working pressure and temperature, and the fluid. For a KPR regulator we also need inlet pressure, the outlet control range and the port configuration.Browse Swagelok products by category: Pipes & Fittings, Regulators, Fittings & Valves.
