Swagelok SS-83KF8 83 Series Trunnion Ball Valve, 1/2 in. FNPT

Push into high-pressure territory with the SS-83KF8 trunnion ball valve. This three-piece 83 Series design rates to a stout 6000 psig, so you shut off aggressive process and hydraulic lines with total confidence. The trunnion-mounted ball carries the load on its stem, which drops your operating torque and lets you turn the valve smoothly even under pressure. You get a 316 stainless steel body, firm PCTFE seats, and 1/2 in. female NPT ends that thread straight into your existing pipe runs. A 1.2 Cv path through the 0.187 in. orifice gives you controlled, positive shutoff where leak-tight sealing matters most. Mount it on high-pressure sampling, hydraulic test stands, and gas distribution skids and trust it to hold. The compact three-piece body still swings out for seat service, so maintenance stays simple. Need a locking handle, alternate seats, or tube-fitting ends instead of NPT? Collins-Oliver builds the exact 83 Series trunnion valve your job calls for. Call for your quote.
