The EV20-S34 is a screw-in, cartridge style, hydraulic directional element. It is a spring biased blocking valve which will shift to allow full flow from port 1 to 2 only when port 3 is vented to create a pressure drop across the internal orifice which exceeds the bias spring pressure value.
NOTE: Orifice disc should not be used with this product.
- Multiple function/application potential.
- Smooth shift transition.
- Low pressure drop.
- Industry common cavity.
