Male-Threaded, Grooved and Plain End Check Valves

Design Features

The stationary hinge-post and hinge-clamp design reduces wear to hinges, pins, valve seats, springs and the need for routine maintenance.

The valve plate design reduces travel from a fully open to fully closed position and provides complete metal-to-metal valve plate structural support, resulting in a non-slam, quick closure feature.

Our unique flexible elastomer seal provides final closure around the valve bore with continuous strength and durability to ensure prolonged cycle life, outwearing traditional metal-seated valves.

Technologically Advanced Internal Design

Engineered elastomers, developed for durability beyond the range of ordinary elastomers, provide the hinge and the seal in our unique patented TECHNO design. These tough, flexible, reinforced elastomers are resistant to liquids, gases, steam, chemicals, oil and fuel. The strength and durability of these elastomers prolongs life cycle. The unique resilient seal also provides tight shutoff.

Features include:

Large free area with resulting low pressure loss
High sealing integrity from the continuous seal design
Reduced noise and wear by elimination of metal-to-metal rotating parts
Stable operation under a wide range of flow rates
