UNI-CHEK® Check Valves

Uni-Chek® Check Valves provide check valve performance with large opening angle resulting in high Cv performance. Much lighter and easier to handle and maintain than conventional swing check valves they provide an economic solution and protection for systems with a low reverse velocity.

Features And Benefits

  • Compact and lightweight design versus conventional swing check valves which saves time and money with ease of installation.
  • Available in sizes 2″ (50mm) through 36″ (900mm), and pressure classes to meet ASME, BS, DIN, AS, JIS and ISO standards.
  • Single disc–spring closure — provides unobstructed flow, bubble-tight O-ring seal, with good dynamic response to reduce damaging water hammer.
