FLDA Series Hydraulic Valve, Plug-in Filter, FL Series, Interchangeable With SUN

Mainly used for pressure, flow, and direction control in hydraulic systems. The products cover more than 20 categories such as plug-in valves, balance valves, one-way valves, logic valves, etc., suitable for fields such as engineering machinery, ships, and petroleum equipment. Its core design adopts a free floating structure at the end of the valve, reducing installation torque sensitivity and preventing jamming. The internal components have been heat-treated to have wear-resistant and fatigue resistant properties. The socket design utilizes thread centering, eccentricity compensation, and load dispersion technology to support working pressures up to 350 bar and a flow range of 720 L/min. Representative models include CBCA-LHN balance valve, CXBA-XCN one-way valve, RPCC-LAN pressure relief valve, etc. Some products are equipped with EPDM seals to adapt to phosphate hydraulic oil systems. The most significant advantage of SUN plug-in valves is the free floating at the end of the valve. With its tightly fitted working components, it can float inside the valve body, reducing its sensitivity to installation torque and avoiding the possibility of internal moving components getting stuck. Clean or inspect plug-in valves without changing the valve settings or dismantling any piping. The internal working components of SUN plug-in valves are all heat-treated, processed to be wear-resistant, impact resistant, fatigue resistant, and have a long service life. To ensure the reliability of the valve, SUN plug-in valve sockets consider: 1. The outer diameter of the threaded shoulder can guide the valve into the socket to ensure alignment. The eccentricity between the end of the free floating part socket plug valve and the plug hole. The floating design of the 3 SUN plug-in valve allows for higher installation torque, making the valve more securely tightened to avoid loosening or oil leakage. The shoulder flat mouth serves as a stopper to withstand the load caused by the thread, avoiding any load or deformation of the plug-in valve, and ensuring the alignment of the centerline. Place the thread in the center position to maximize the valve's flow capacity and reduce the impact of eccentricity, and distribute the thread load in the deep layers of the oil circuit plate. The stopper at the bottom of the 6-socket supports the floating part of the valve, while the assembly wire is only used for valve assembly. The consistency of the 7 SUN oil ports provides greater flexibility in design and reduces the need for cutting tools on the oil circuit board.
