	Hydraulic Directional Control Valve 16.8 GPM, 4500 PSI 4-Way, 2-Position Spring Offset Closed Crossover Spool Type 120 Volt AC This industrial hydraulic directional control valve conforms to the National Fluid Power Association (NFPA) D03 mounting pattern for subplate or manifold mounting. As a four-way valve, it is commonly used to extend and retract a double-acting hydraulic cylinder. As a single-solenoid valve, it will remain in its home position until shifted electrically, returning to home when the power is removed. Its molded coils are moisture and dirt resistant. Indicating signal lights, manual override, bolt kit and electrical junction box are standard.it is commonly used to extend and retract a double-acting hydraulic cylinder. As a single-solenoid valve, it will remain in its home position until shifted electrically, returning to home when the power is removed.
	The moving components of the solenoid are contained in a pressure tight tube assembly, eliminating dynamic seals and the related mess and expense of leaks. Additional advantages include superior life due to hydraulic fluid lubrication of the armature, easy coil replacement without opening the hydraulic system, and ease of valve assembly. Seven basic sizes combined with many optional features allow these solenoids to be tailored to meet your specific requirements. Custom designed solenoids are welcomed.It is level a control valve developed from advanced energy-saving technology introduced from abroad. It is very reliable and energy-saving.Its upper and down parts are tightly sealed to ensure reliable close. It is mainly used in various automatic water supply system of pools, water tower and so on.
	In-line mount 17.1 GPM flow 3000 PSI max. pressure rating 1/2in. NPT female ports Free flow one direction, blocked flow opposite direction This Northman in-line check valve is designed to allow free flow of oil in a hydraulic system in one direction and block flow in the reverse direction. It is roughly composed of valve body, valve clack, piston rod, bonnet spring and other components. When the water level of a water tower drops, float valve is open, and the pressure reduces forming pressure difference between the above and below piston. Driven by this difference,valve clack is opened and water begins to flow in. When water level rise to the control level, the float valve closes, and the pressure increases. At that time the valve clack is closed and due to that the pressure above the piston is greater than the pressure below.With such a repeating circulation, it is able to supply water automatically.
