Full Product Description

Parker non-return valves with an ISO 8434-2 (Triple-Lok®) or 8434-3 (O-Lok®) connection offer a wide range of sizes, male threads and cracking pressures, making them very flexible.
The principle of a two-part non-return valve with an integrated soft sealing element has been proven by many applications in the market.
This reliability is the reason for its successful use in applications with Triple-Lok® (37° flare) or O-Lok® (O-Ring face seal).
Parker non-return valves are available with Cr(VI)-free surfaces. The broad product range goes from sizes 4 to 24 (6 mm to 38 mm O.D.); UNF, BSPP and metric male threads are available. The cracking pressures are from 0.2 to 6 bar. The maximum flow velocity is 8 m/sec. The nominal pressure PN: Triple-Lok® up to PN 350 bar and O-Lok® up to PN 400 bar.

Features/ benefits of SAE non-return valves:
• The precise functioning of Parker SAE non-return valves has been proven a million times over and stands for the reliability of this product range.
• Combined soft and metal sealing – leak-free due to soft sealing at cone and metal-supported sealing at cone – extends the safety of the product and the entire hydraulic application.
• The usage of Parker SAE non-return valves is flexible due to the wide range of cracking pressures available.
• For yet more applications, internal parts in stainless steel with FPM are also available.
• The wide range of male threads also increases the number of potential applications.
