Product catalog summary

Overview: The document provides technical specifications and descriptions for directional control valves and shut-off valves, focusing on the Kegel-Sitzventilpatrone SP3 and Wegeventil WLA3 models. These valves are designed for high-pressure applications with compact dimensions and efficient performance.

Specifications:

Kegel-Sitzventilpatrone SP3: Direct-acting, pressure-tight in both flow directions, available in 2/2- and 3/2-way versions. Maximum pressure is 250 bars with a flow rate of up to 8 l/min and a nominal diameter of 3 mm.
Wegeventil WLA3: A 4-way spool valve, solenoid-operated, with a maximum pressure of 250 bars and a flow rate of up to 8 l/min. It features a compact design with a nominal diameter of 3 mm.

Functional Description:

The SP3 series is characterized by pressure-balanced operation, allowing for high switching performance in a compact size. The hydraulic ports are adaptable for various configurations, and the solenoids are integrated for a low-profile design.
The WLA3 series features a 5-chamber spool design for reliable switching, even after long periods of inactivity. It is robust, lightweight, and designed for minimal leakage and noise.

Technical Characteristics:

SP3 Valve: Operates with 12 or 24 VDC solenoids, consuming 16 W. It is mounted using a two-hole flange and is suitable for temperatures between -30°C and +100°C. Recommended hydraulic fluid viscosity is between 10 and 500 cSt.
WLA3 Valve: Operates with 12 or 24 VDC solenoids, consuming 10 W. It is designed for ambient temperatures between -10°C and +80°C, with a recommended fluid viscosity range of 10 to 320 mm²/s.

Installation and Maintenance:

Both valves require specific mounting and connection configurations, with detailed instructions for cavity preparation and installation provided.
Regular maintenance includes checking for leakage and ensuring proper filtration (25-40 µm recommended).

Applications: These valves are primarily used in automation machinery, automotive, and mobile applications, serving as pilot valves or in direct control systems.

Additional Specifications: The document outlines various components and specifications related to HOERBIGER's hydraulic systems, including operation symbols, flow rates, and pressure drops for different components. It specifies connectors, solenoids, and subplates used in hydraulic systems.

Components and Order Codes:

Connectors: AMP - Superseal connectors with a 2-pin cable resistant to hydraulic oil, with a length of 1500 ± 50 mm and a cross-section of 2 x 0.75 mm².
Single Subplate: Model 600.2355 for radial port connection M10x1, suitable for directional control valve WLA3 and stacking system DN3.
Directional Control Valve: Includes solenoid type M with short solenoid and plug AMP - Superseal.

Pressure Valves:

Pressure Control Valve P3B: Direct-acting with damping piston, adjustable pressure stage from 50 to 250 bar, max flow rate of 6 l/min, nominal diameter of 3 mm.
Pressure Relief Valve P3S: Undamped, adjustable pressure stage from 20 to 160 bar, max flow rate of 6 l/min, nominal diameter of 3 mm.
Performance Valve P3R: Cartridge design, direct-acting, max flow rate of 6 l/min, max input pressure of 210 bars, with 3 control ranges.

Flow Control Valves:

Flow Control Valve Q3: Includes lowering brake, throttle valve, and throttle relief valve, with sensitive operating performance, pressure of 210 bars, flow rate of 6 l/min, and nominal diameter of 3 mm.

Beschreibung Description Die Baureihe der direktgesteuerten Kegelsitzventilpa-tronen NG3 zeichnet sich dadurch aus, daR diese Patronen druckentlastet arbeiten und somit bei kleinster Bauweise eine groRe Schaltleistung aufweisen. Je nach Anwendung knnen die lanschl䔹sse frei belegt werden, da diese von allen DurchfluRrichtungen her verwendet werden knnen. Der VentilstBel wurde in den Magneten integriert, um eine m䴴glichst gedrungene BaugrBe zu erreichen. Aus der Darstellung ist das Funktionsprinzip ersichtlich.

HOERBIGER Das Ventilgehuse ist aus hochfestem HydraulikguB und der Kolbenschieber aus gehrtetem Stahl gefertigt. Die Ventile sind trotz ihres kleinen Bauvolumens robust und unempfindlich und somit auch fur rauhen Betrieb geeignet. The valve body is made of high tensile cast iron and the spool of hardened steel. Despite their small size, these valves are robust and insensitive and therefore suitable for rugged operation.
