Electric and pneumatic actuators are both widely used to automate ball valves and butterfly valves. Choosing between them is not simply a matter of deciding which actuator is "better."The right choice depends on five main factors: the available power source, required fail-safe position, operating sp

Learn the difference between Air-to-Open and Air-to-Close pneumatic valves and how they relate to Fail-Open and Fail-Close operation. This guide explains spring-return actuator behavior, common fail-safe applications, and how to determine the appropriate valve position when air or control is lost.

SLVCN will attend CAOG 2026 at Booth A22 to meet industry partners, understand real project needs, and discuss customized valve solutions for oil & gas and industrial applications.

Our team participated in Indo Water 2025 Expo & Forum in Jakarta, showcasing a wide range of valve solutions, including ball valves, butterfly valves, and actuators. Through discussions with industry partners and customers, we explored valve applications in water treatment, wastewater management, seawater desalination, and industrial recovery, while gaining valuable insights into the Indonesian market and strengthening future cooperation.

Choosing the right butterfly valve body material is critical for performance and service life. This article explains the strengths and limitations of the most common materials — including cast iron (FC), ductile iron (FCD, GGG40, GGG50, DI), carbon steel (WCB, A105), stainless steel (CF8/CF8M), duplex stainless steel (2520, 2507), aluminum bronze, and plastics (PVC, CPVC, PVDF). We cover where each material fits best: from water and HVAC pipelines to chemical, marine, and high-temperature applications. A quick selection guide with corrosion resistance ratings helps buyers make faster, smarter decisions.

SLVCN completed the shipment of DN40 and DN50 pneumatic PTFE-lined wafer butterfly valves with double acting pneumatic actuators, limit switches, and DC24V solenoid valves for a customer in Southeast Asia.
