The FFP valve is a reliable safety component designed to protect hydraulic systems against sudden oil loss caused by unexpected installation failures such as hose ruptures. Under standard operating conditions, it ensures unrestricted bidirectional oil flow, maintaining smooth and efficient system performance. In the event of a rapid flow increase, the valve immediately reacts by shutting off the oil stream in one direction, effectively preventing further leakage and safeguarding both equipment and operators. With a permissible flow direction of A → A1 (free) and A1 → A (controlled by the valve), it guarantees precise functionality tailored to demanding hydraulic applications. Manufactured from durable carbon steel with a galvanized body and a hardened steel valve, it offers exceptional strength and resistance to wear. The robust metal-to-metal sealing ensures long-lasting tightness, even under intensive use. Designed to operate reliably in a wide temperature range from -30°C to +100°C, the FFP valve delivers consistent performance in diverse working environments, making it an essential element for industries that prioritize safety, efficiency, and system durability.
