Part number 1SH20-S is a Vickers 1SH Series check valve from Eaton, now under Danfoss Power Solutions. It is a ball style check valve in the SICV check valve family, so it matches that 1SH series type.

what's the flow rate on this check valve, the 1SH20-S? trying to figure out if it'll keep up with what we got running on our refuse hauler

Answer by: Customer Support on May 9, 2025, 8:50 PM

Rated at 20 litres per minute, this valve sits within a series that's built to handle up to 227 L/min (60 USgpm) at pressures up to 350 bar (5000 psi). For refuse hauler applications, that combination of high pressure tolerance and efficient flow handling is exactly what the 1SH series was put together for.
