Industrial Valve Types and Applications - The .

Not only does globe valve design support control, but many valve bodies allow interchangeable inner parts, so the orifice in the middle can be larger or smaller depending on the user's needs. However, globe valves restrict flow more than other valves; ball valves can offer 30% - 40% higher flow rates. Valve .

INTRODUCTION TO VALVES

Ball Valves, as the name implies, have a ball with a hole drilled through the centre swivel mounted within the valve body. When the hole in the ball is orientated in the same direction as the pipe, this will result in full flowrate. As the hole in the ball is oriented away from the direction of the pipe, the flowrate will be restricted and finally cut off completely when the hole is oriented ...

Check valves and non-return valves | Heating & .

Design differences of non-return valves and check valves For non-return valves the simplest design is the swing valve, with a weighted flap which is held open by forward flowing water. If flow reverses it closes under its weight and is kept shut by backpressure acting on the closed flap. The wafer flap valve is a slimmer version of the same design. Other designs include the tilted plate NRV ...

Types of Valves and Their Applications and .

Ball valves can be designed so that friction loss through an open valve is no greater than what would be encountered in a like diameter pipe (also making them piggable in some cases). Other valve types usually introduce some loss in the valve owing to the need to place the components of the valve, actuating shafts, etc. directly in the stream and/or the need to redirect the direction of fluid ...
