SPC1-10 Series Inline Single Pilot Operated Check Valve, Main Ports, SAE-4 Pilot Port

Description & Features

The SPC1-10 Series Inline Single Pilot Operated Check Valve Main Ports SAE-4 Pilot Port ensures high efficiency and reliability for industrial applications handling pressures up to 3000 PSI.

With a flow rating of 12 GPM and a cracking pressure of 15 PSI it guarantees optimal performance. The valve's Buna-N seal material ensures durability within a temperature range of -40F to 248F.

Features include a pilot ratio of 4:1 contributing to precise control and smooth operations. The recommended filtration level is ISO 4406 Cleanliness Level 18/16/13 or cleaner enhancing system dependability.

**Model Number:** SPC1-10-P-8T

**Supplier Part Number:** 565875

**Manufacturer:** Danfoss (Power Solutions II LLC)

This check valve is suitable for applications such as locking a cylinder without leakage while the control valve is in a neutral position. It prevents movement of a load when the pressure source is inactive making it ideal for pilot-operated check valve circuits that require a 4-way control valve.

Note: Follow all catalog recommendations and application directions. Always use mechanical supports when servicing or removing the valve due to possible trapped pressure in the holding valve circuit.

What size ports does this check valve have?
Answer by: Customer Support on Jul 30, 2025, 6:34 AM
The main ports are 1/2" and the pilot port is SAE-4.

what kind of pilot pressure do i need to unlock this thing on a single acting cylinder?
Answer by: Customer Support on Mar 23, 2026, 6:53 AM
For single acting cylinders, the unlocking pilot pressure works out to 25% of the locked pressure. So if you've got 1000 PSI holding a load, you'd need around 250 PSI in the pilot circuit to open it up. Keep in mind a 4-way control valve is required in the circuit even for single acting setups. That's not optional. The pilot port on this valve is SAE-4 size, so make sure your pilot line connection matches up before you start hydraulic connections it in.
