Goodwin's streamlined flow path through an Axial Control Valve has minimal pressure drop. The flow is directed through the valve to avoid critical sealing areas, promoting the longevity of the seat sealing arrangement. With an annular flow area and an unrestricted, symmetrical, streamlined flow path through the valve, Axial Control Valves have a higher inherent flow capacity compared to conventional globe control valves.

The streamlined flow path through an Axial Control Valve has minimal pressure drop and the flow is directed through the valve to avoid critical sealing areas promoting longevity of the sealing arrangement.
With an annular flow area and an unrestricted, symmetrical streamlined flow path through the valve, Axial Control Valves have a higher inherent flow capacity compared to other control valves.
Pressure balancing is equally effective in both forward and reverse pressure conditions and can be opened against full differential pressure.
With pressure energised seals encapsulating the piston body and pressure energised seating seals in the piston head, tight shut-off to FCI 70-2 Class VI, i.e. bubble tight, can be achieved.
Where process conditions permit, i.e. a single stage pressure let down, flow can be bi-directional. Standard is Uni-directional.
Through FET testing witnessed by Lloyds Axial Control Valves have been certified to Rate A Class (HS) of ISO 15848-2 which is the tightest rate achievable.
Goodwin Axial Isolation Valves utilise Goodwin's patented Rack-Pinion-Rack gear train mechanism to transpose the linear motion of the actuator through 90° into axial motion of the piston which provides: High durability, rapid and precise movement. Closure in less than 2 seconds. High rangeability. Zero risk of gear teeth seizure with minimal or no lubrication. Low friction and high efficiency compared to sliding gear mechanisms. Low backlash maintained over the lifetime of the product.
