The solenoid operated air valves of this series are types with an internal-pilot-type metal seal and a spool valve.This provides a choice of 3-way (3 ports), 4-way (5 ports), 2-position with single or double solenoid, and 3-position with closed center or exhaust center models, in conformity with customer's requirements.
FEATURES
Small, Light and High Flow RateThe compact size is achieved by the well-designed flow path construction and aluminum-alloy bases and small pilot solenoid valves, and a larger Cv Factor as well as a light weight are being accomplished for its sizes.
Long Service Life
The valve incorporates a metal seal system composed of a sleeve and a spool on which KURODA's super precision machining technique in making various kinds of gauges are embodied. The sleeve and spool assembly is made of special stainless steel that provides anti-corrosion and is being hardened at Rockwell C60 for anti-weariness. Besides the assemblies being made to fit with a several micron clearance one another results slightest air leak and allow the spool to float in the sleeve. Accordingly this not only can be used under without lubrication but also assures a long service life for its small friction that affects a minimum wear and high sealing effects.
No Coil Burn Out
These valves are operated by pneumatic power to shift the spool to obtain greater shifting force. And because of its small resin-molded solenoid coil a low power consumption is expected. This coil will not burn out in cases of sleeve or spool malfunction which would be typical causes for failure by presence of deteriorated compressor oil, pipe scale, sand or unnecessary viscous oil in the lubricator if a direct operated valve was used.
Quick Response and Positive Shifting
Minimized internal volume of the pilot portion provides short response time though a pilot type. Pneumatic power gives a greater shifting power for positive switching of the spool.
Plug-in Connector
A plug-in connector (DIN43650) is used in the electric joint portion for the ease of connection. The conduit opening of the connector can be directed in any direction.
Locking Manual override
To enable manual operation, a locking button of KURODA's unique design comes as option. (None lock manual override is standard)
Flow Pattern
As the standard solenoid valves are internal pilot type, air pressure must be fed from its port 1. But by plugging other ports these can be used as 2-way, 3-way, or 4-way valves.
Mounting
These solenoid valves are sub-base mounting types in discrete use but manifold mounting isavailable for the demand of combination use (except for 3-way model). The same interface is being placed between the valve body and sub-base as used with KURODA's direct operated solenoid valves so that these valve bodies are interchangeable with the direct types
