This guide provides an overview of the WAALPC S4V Series stainless steel solenoid valves for demanding industrial environments. The series includes S4V410-15 (5/2 single solenoid), S4V420-15 (5/2 double solenoid), and S4V430C/E/P-15 (5/3 double solenoid with three center options). All models feature stainless steel bodies, 1/2" ports, 0.15–0.8 MPa operating pressure, –20°C to 70°C temperature range, and IP65 protection. Key features include pilot-operated sliding spool design, manual override, manifold mounting, and no lubrication required. Flow rates are 48.0mm² (Cv=2.82) for 5/2 models and 40.0mm² (Cv=2.35) for 5/3 models. Coil options include AC220V, AC110V, AC24V, DC24V, and DC12V. Applications include chemical, marine, food, pharmaceutical, and industrial automation. Installation, maintenance, troubleshooting, and selection guidance are also covered. Read More

This comprehensive guide provides an in-depth overview of the WAALPC ARM Series miniature pressure regulators, a family of compact pneumatic components designed for space-constrained, high-precision applications. The series includes two main model families: ARM5S, an ultra-compact single-unit regulator with a width of only 14mm and weight of 33g, and ARM10, a small manifold regulator weighing 60g with flexible configuration options including selectable knob position (top/front/bottom), piping direction (top/bottom), and digital pressure switch compatibility. Both models feature direct-acting design, standard overflow structure, standard reverse flow function, maximum working pressure of 1.0 MPa, and pressure setting range of 0.05–0.7 MPa (with low-pressure 0.05–0.35 MPa option available). The article covers working principles (piston-type for ARM5S, diaphragm-type for ARM10), technical specifications, connector configurations (straight joints and pipe bends, Ø4/Ø6 or Ø5/32"/Ø1/4" tube Read More
