FAQ

What is the function of the 'pilot-operated' feature in this check valve subplate?

The pilot-operated feature allows the check valve to be opened with an external hydraulic signal (pilot pressure). This permits reverse flow, which is essential for retracting cylinders or lowering loads in a controlled manner, something a standard check valve cannot do.

The '0.4' specifies the pilot ratio of the check valve. A pilot ratio of 0.4 means that the pilot pressure required to open the check valve against the main line pressure is 40% of that main line pressure. This ratio is critical for system stability and operation.

'V' stands for Viton (FKM) seals, which offer excellent resistance to high temperatures and a broad range of chemicals, including mineral oils, synthetic fluids (like HFD), and fuels. However, they are not recommended for use with certain fluids like ketones or ethers. Always verify fluid compatibility before installation.
