Optional Flameproof Dust or Non-explosion-proof Solenoid Valve
The MSV400 solenoid valve supports two versions: flameproof & dust explosion-proof type for hazardous locations, and non-explosion-proof type for common industrial environments, helping customers save cost on non-explosion occasions. It adopts pilot-operated control principle and 2-position 3-way / 2-position 5-way air circuit structure.
The valve supports surface mounting and pipe mounting. Operating temperature covers T6/T5/T4, medium temperature range -40℃ ~ 130℃. Standard voltage: 24VDC and 220VAC, IP67 ingress protection.
Housing materials can be aluminum alloy, stainless steel or brass. Air port connections: G1/4, 1/4NPT, 1/2NPT. Electrical connection includes M20*1.5, 1/2NPT. Suitable for general and dust explosion risk automation pipelines.
