ARL 45 Degree ‘Y’ Type Check Valve

The Atomac ARL ball check valve is ideal for conveying highly corrosive acids having a solid PTFE ball housed within a robust PFA lined cast body. Under normal flow conditions the solid PTFE ball is dislodged from it’s seat and pushed out of the flow allowing fluid to pass through the valve body unhindered. If the flow reverses gravity pulls the ball back into its seat preventing backward flow through the valve. Ideal for slurry applications or low flow rates. The non-return ball check valve is available to suit both ASME B16.5 class 150 and DIN PN/10 piping systems.

The valve body is PFA lined ductile iron body with stainless steel fasteners. The PFA liner is securely locked in to its housing with machined slots.  The use of PTFE and PFA for wetted parts means that it has near universal process corrosion resistance.
