Description & Features

The SPC1-16 Series Inline Single Pilot Operated Check Valve, Main Ports, SAE-6 Pilot Port by Danfoss ensures precise control with 350 bar (5000 psi) pressure capacity and 227 L/min (60 USgpm) flow rate. This check valve, designed for industrial applications, operates efficiently with low spring settings and a pilot ratio of 4:1. It features a maximum operating pressure of 3000 PSI and a flow rating of 40 GPM.

The valve uses a Buna-N seal material and has a recommended filtration level of ISO 4406 Cleanliness Level 18/16/13 or cleaner. The temperature range extends from -40deg;F to 248deg;F, making it versatile for various environmental conditions. The 3/4" port size and SAE-6 pilot port size ensure compatibility with standard industrial equipment.

Important lock valve basics include adherence to catalog recommendations and application guidelines. When servicing or removing the valve, ensure that trapped pressure is carefully bled down to prevent hazards. For double-acting cylinders, unlocking pressure calculations involve the locked pressures at both cylinder ends.
