The Masoneilan 28000 VariPak is the industry-standard micro-flow control valve specifically engineered for precise regulation of extremely low flows in laboratory, pilot plant, and research applications. With ten interchangeable plug-and-seat trim sets covering Cv from 0.001 to 4.0 and a field-adjustable 10:1 turndown, it offers unmatched flexibility without changing the valve body. The compact ¾" angle body with ANSI 900/1500# end connections and heavy-duty bellows or graphite packing ensures ANSI Class VI shutoff even at high pressures. Trusted for over 50 years in catalyst injection, dosing, and sampling systems worldwide.
