SKE GVS Series Industrial Solenoid Valve

Product Overview

The SKE GVS Series Industrial Solenoid Valve is a high-performance, general-purpose fluid control valve developed for demanding modern industrial environments and automated piping networks. This series uses a direct-acting solenoid coil to drive the valve spool directly, requiring no pilot air supply whatsoever. This breaks the traditional pilot-operated solenoid valve's dependence on media pressure, achieving true minimum working pressure start-up.

To address the complex media and operating environments found on industrial sites, the GVS series introduces an ultra-low-friction PTFE guide ring and graphite-filled seals. Whether handling routine air and water fluid distribution, or operating in hazardous, explosion-proof-rated areas such as precision new-material production, the GVS series ensures rapid response and extremely high reliability over long-term operation.

Core Advantages and Features:

● Direct-Acting Zero-Pressure Operation:Uses manual reset and direct-acting solenoid drive, requiring no pilot air supply. Delivers excellent flow performance at equivalent power consumption, with a flow coefficient (Cv) of up to 0.45.

● Anti-Sticking and Long Service Life:Core moving parts are equipped with a PTFE guide ring and graphite-filled seals, greatly reducing internal friction and effectively preventing the valve from "sticking" after long-term operation or idle periods, extending service life.

● 3/2 Universal Flow Path Design:Features 3-way, 3/2 universal functionality. The inlet port can be flexibly connected, supporting normally open, normally closed, diverting, or converging fluid logic, reducing plant spare-parts inventory requirements.

● Pure Materials and Dry Seal:The valve body is made of industrial-grade 316 stainless steel, equipped with a 1/4" NPTF dry-seal tapered pipe thread connection, meeting demanding process requirements for high cleanliness and corrosion resistance.

● Wide Voltage Range and Safety Protection:Supports a wide range of AC/DC voltage standards (including 125 DC and 250 DC battery-charging characteristics), adapting to various power environments. Meets requirements for hazardous areas and diverse indoor/outdoor operating environments, with multiple protection ratings including CSA, UL, and Type 1 through Type 9.

Application Scenarios

1. Alumina Smelting and Refining

Requirements and Fit: Alumina sites readily generate dust and scale, and some areas are classified as hazardous. The GVS series' stainless steel valve body and PTFE guide ring anti-sticking design maintain stable direct open/close operation in dusty and harsh environments, with no concern about pilot orifice clogging.

2. Silicon-Carbon Anode Material Production

Requirements and Fit: Silicon-carbon anode production requires strict media purity. The GVS series' NPTF connection achieves a tight dry seal without additional PTFE tape that could flake off; its stainless steel construction avoids heavy-metal ion contamination, while its hazardous-area rating ensures process safety.

3. General Hazardous Areas and Standard Operating Conditions

Supports indoor, outdoor, and various hazardous-area installation environments; with its 3/2 universal structure, it is widely applicable for precise control in automated diverting, shut-off, and distribution systems for media such as air and water.
