Note: Data may vary by configuration. See CONFIGURATION section.

• The valve allows free flow from port 1 to port 2 and blocks flow from port 2 to port 1 for holding a load. Flow will not be allowed from port 2 to port 1 when pressure is applied to port 3. Nominal pilot ratio is 1.8:1. This means that a pressure of 100 bar (1400 psi) at the pilot port (port 3) will close a valve against a pressure of 180 bar (2600 psi) at port 1.
• Internal components are made of high-quality materials, processed heat treatment and precision grinding to achieve excellent wear resistance and protection against contamination for long-lasting durability.
• This valve does not permit the flow from port 2 to port 1 under any circumstances.
• The valve will close when all ports reach the same pressure.
• The pressure at port 2 affects the pilot-to-close pressure at port 3 in a 1:1 ratio.
• External components are WINNERcoat^® Zinc-Nickel Plating for 1000 hours salt spray test according to DIN EN ISO 9227. Ordering code with letter "P" at the end is stainless steel external components. 
• Winner guarantees that all products performance a 100% functional test before shipment.
