• Smooth non-reversing flow characteristics
• Constant flow at any given stem position
• Fifteen turns full open to full close provides high turn to lift ratio for excellent resolution
• Six interchangeable needle tapers, each increases capacity by an approximate factor of three
• O-ring seal cannot be damaged by overtightening
• Panel mounting nuts included - standard
• 1/8" NPT connections integrally machined into body
Control valves are designed specifically for extremely low flow gas and liquid applications. Straight and 90° angle pattern models in stainless steel are available. They feature a means of adjusting a sliding tapered needle which prevents sticking due to foreign matter in the fluid. These valves are particularly suitable for precise control requirements and possess a high turns to lift ratio. The flow is constant for any given stem position.
Six needles with different tapers provide a wide choice of flow ranges. Needles and
orifices can be changed without removing the valve body from the line (two different
orifices are used, one for needle sizes 1-3, another for sizes 4-6).
