Product Overview
The VERIFLO 42500426 is a high purity diaphragm valve engineered for critical gas and liquid delivery systems where media containment and contamination control are paramount. Manufactured by Veriflo (a Parker Hannifin brand), this valve utilizes a flexible diaphragm as the sole moving wetted component, isolating the actuator mechanism from the process media. This design eliminates packing, seals, and sliding stem interfaces that can trap particles or generate entrained contaminants, making the 42500426 ideal for semiconductor, pharmaceutical, and analytical instrumentation applications requiring ultra-clean service. The valve provides reliable on/off flow control with a compact, panel-mountable body configuration.
