These are special double shut-off couplings for hydraulic duty condition upto 700 Kg/cm2 (10000 PSI) ideally suitable for high pressure hydraulic circuits. The DV-700 series is not simple modified version of another coupling series but has been designed and constructed specifically for high pressure hydraulic application. The DV- 700 series has proved a record of reliability on tough hydraulic test stand applications where high pressurisation is a must. Application : High pressure hydraulic application, ideal for test stands and applications where cleanliness is required, permits easy tool changeover, oil fields, off-shored drilling, cranes, power tools etc. Features: Heavy duty construction. Superior flow characteristics. Low pressure drop Push to connect. Teflon supporting ring is provided to have longer seal life. Sizes : 1/4" to 1". Material : Carbon Steel Working Pressure: Upto 700 Kg/cm2 (10000 PSI). Safe pressure 12500 PSI. Failure pressure 15000 PSI. End connections : BSP Female Threads. Seals : Nitrile, Viton etc.. Shut-off Combination : Double shut-offs.
