J941H, J941Y, and J941W electric flange globe valves and flange gate valves belong to the same type of valves. They consist of two main parts: an electric actuator (or pneumatic actuator) and a globe valve. The distinguishing feature is that the closing element is a disc that rotates around the valve body’s centerline to achieve opening and closing functions.
J641H, J641Y, and J641W pneumatic globe valves adopt double-acting cylinders, which use air intake from the upper or lower cylinder chambers to remotely control the valve, featuring convenient and flexible operation.
Medium for Cylinder: Compressed air, nitrogen.
J41T/W/H/F-16 gray cast iron globe valve, connected by flanges, belongs to the forced sealing type valve. When closing the valve, pressure is applied to the valve disc to force the sealing surface to be leak-proof. When the globe valve is opened, the flow rate reaches the maximum when the opening height of the valve disc is 25% to 30% of the nominal diameter, indicating that the valve has reached the fully open position.
The J941H electric flange globe valve is composed of two parts: an electric actuator and a globe valve. The opening/closing component of the electric flange globe valve is a plug-shaped disc with a flat or conical sealing surface, and the disc moves linearly along the central axis of the fluid. The electric globe valve is only suitable for fully open or fully closed states and is not allowed for regulation or throttling.
