<\/p>\nTECHNO Dual-plate, Metal-hinged Wafer-style Check Valves<\/strong><\/p>\n
- \n
- Compact wafer-style, one-piece design<\/li>\n
- Center post fully supports the internal assembly without external pins or plugs<\/li>\n
- No fugitive emissions to atmosphere is ensured due to its standard design, which eliminates through holes and pipe plugs in the body<\/li>\n
- Maximum flow area reduces pressure loss<\/li>\n
- Reduces installation space and time<\/li>\n<\/ul>\n
VALVE PLATES
\nThe dual-plate design produces increased strength with reduced opening and closing time.<\/p>\nCLAMP PLATES
\nClamp plates offer additional strength to valve plates and allow seals to be changed easily.<\/p>\nSEALS
\nSpecially designed flat, full-contact seals maintain positive shutoff at low working pressures. Unlike most other valves, these seals are replaced easily in the field.<\/p>\nSPRINGS
\nTorsion springs assist valve plate closure, preventing flow reversal. Consistent valve response ensures against slamming and water hammer.<\/p>\nSHAFT
\nThe shaft features heavy-duty, corrosion-resistant construction.<\/p>\nSHAFT SUPPORTS
\nShaft supports act as stops to prevent over-travel of valve plates. They are corrosion resistant with large shaft-bearing surfaces and are easily removable for internal assembly, maintenance or change.<\/p>\nTHRUST WASHERS
\nThrust washers reduce friction and wear of valve plate hinges.<\/p>\nVariety of Configurations<\/strong>
\nTechno offers a wide variety of wafer bodies in different styles and materials. These can be assembled with different disc, spring, and elastomer seal choices to make a valve that exactly fits your application. Contact pdblowers if you would like a quote on any of these options.<\/a><\/p>\n\n\n
