The SK series represents a versatile range of pneumatic control valves manufactured in G1/8 port size, engineered to deliver precise automation across multiple configurations. Available in 3/2, 5/2, 5/3, and dual 3/2+3/2 valve arrangements, these solenoid-piloted units offer exceptional flexibility for both standalone and manifold-integrated installations. The 22mm integrated solenoid actuator (SK822) provides reliable electrical control, while the compact dual-valve design eliminates the need for separate assemblies without compromising performance. These valves meet demanding industrial standards and are available in ATEX-compliant variants (category 3GD and 2GD) for hazardous environment applications. Whether configured as monostable or bistable units, the SK series adapts seamlessly to complex pneumatic systems while maintaining consistent switching accuracy and durability across diverse operational environments.
