The flow control valves starting from inlet pipe dia. DN 200 and upward are designed for axial flow, and therefore a safety shut-off valve cannot be included. The proven valve sleeve system is used, thus enabling complete inlet and outlet pressure compensation. The valve sealing situated in the valve cone guarantees bubble-tight shut-off of the device. The electric actuator positions the valve sleeve by turning a worm wheel which then turns a sleeve with gearwheel fixed on to the valve sleeve. As the gearwheel sleeve also runs in a threaded outer ring, the rotation of the valve sleeve moves the valve sleeve backward and forward.
The main valve has a integrated noise reducing outlet duct as standard. The principle of multiple expansions, the division of the gas stream and the local confinement of the complete expansion guarantee a noise level reduction of 20 dB(A) to 30 dB(A) compared to a standard valve fitted with valve plate and valve seat.
The flow control valve HON 530 works combined with electronic flow- or pressure-controlling regulating systems. It is used specially where great flow values have to be achieved at minimal pressure differentials. Two different designs are used. For size up to DN 100/200 two different body versions are available: - body without safety shut-off device (body of HON 502). - body with integrated safety shut-off device (body of HON 503). The electric actuator mounted on top of the main valve pushes the valve sleeve into the required position via a threaded axle. For sizes DN 80/100 and DN 100/200 identical actuators and valve sleeve parts are used. The max. valve sleeve opening corresponds to the inlet diameter. Rubber sealings guarantee a bubble-tight shut-off when the valve is closed. The special arrangement of the expansion bore holes provide a equal percentage (hyperbolic) and linear characteristic curve. The bore holes also guarantee a noise reduction of up to 15 dB(A) compared to standard valve arrangements with valve plate and valve seat. Further noise reducing elements can be added, thus reducing the noise level up to 30 dB(A). Please note that these elements also reduce the flow rate (KG-value) by 10%.
The main valve is easily maintained as only the valve sleeve and the expansion sleeve have to be removed from the body.
