Introduction

Spreader Valves

GeneralFluid Controls is the worlds largest manufacturer of spreadercontrol valves, and has provided the market with a wide variety ofoptions. The primary use is ice and snow control for many city,county and township sand/salt spreader vehicles. Valves havealso been applied on many agricultural fertilizer spreadersystems, as well as construction paving equipment.

Fluid Controls Spreader valves can provide:• Single compact body permitting easy installation.• Manual or remote electrical control.• Load sensing capability.• Single or dual control.• Pressure compensation.• Gasket mounted configurations

Single Flow Regulator, Adjustable and Pressure Compensated,with Manual On/Unload Control and Relief

Max inlet flow 150 I/min. Max reg. flow 115 I/min and 140 bar

Specifications• To 150 bar.• Inlet flow to 150 l/min.• Regulated flow to 115 l/min.• Weight: 2,90 kg.

Features• Honed and matched hardened steel

working parts for long life.• Rugged, dirt tolerant and reliable.• Adjustable and detented hand knob

with min. & max. stops. 11 positive,easy to adjust positions.

• Fully pressure compensated.• On/unload lever control with detented

stops.• 100% performance tested.

Use and OperationFor use with fixed displacement pumpsin circuits that require a single pres-surecompensated flow control, manualon/ unload and pump relief. Ideal forspeed control of an actuator whichmust have a specific flow setting.Typical machinery applications include

agricultural equipment, salt and cinderspreaders and paving machinery.The valve maintains constant regulatedflow even with changes in loadpressure or input flow. The pressurecompensated regulating sectionbypasses excess pump flow to tank.The tank or bypass port must bereferenced directly to tank and not to aworking line. The direct acting reliefvalve senses system pressure andprotects the pump from shock oroverload pressure surges. The built-inlever operated two-way valve unloadssystem flow to tank. This allows on-unload control of regulated flow withoutchanging the flow setting. In the unloadcondition a 4,5 bar check valve may berequired in the »A« port, »T« port orboth to reduce the potential of motormovement.

Materials• Body – High-strength aluminium

alloy.• Internal parts – Hardened steel.• Seals – Viton A standard.

• Fully pressure compensated.• 100% performance tested.

Use and OperationFor use with fixed displacement pumpsin circuits that require a single pressurecompensated flow control, solenoidvalve for on-unload and pump relief.Ideal for speed control of an actuatorwhich must have a specific flow setting.Typical machinery applications includeagricultural equipment, salt and cinderspreaders and paving machinery.

The valve maintains constant regulatedflow even with changes in loadpressure or input flow. The pressurecompensated regulating sectionbypasses excess pump flow to tank.The pump operates at load pressureplus control section pressure drop. Thetank or bypass port must be referenceddirectly to tank and not to a workingline. The direct acting relief valvesenses system pressure and protectsthe pump from shock or overloadpressure surges. The built-in solenoidoperated two-way valve unloadssystem flow to tank. In the unloadcondition a 4,6 bar check valve may berequired in either the »A« port, the »T«port or both ports to reduce thepotential of motor movement. Thisallows on/unload control of regulatedflow without changing the flow setting.
