Versa’s Needle Valve is a 316 stainless steel, NACE compliant device designed to meter flow in a pneumatic circuit. The flow can be gradually adjusted from zero (closed) to maximum (full open, 10 turns). Constant flow can be secured at the required setting by tightening the lock nut. Flow adjustment is controlled by Versa’s proven needle design from our “Bleed Control” family of products.
