PQ340F PQ340H Eccentric half ball valve

PQ340F PQ340H Eccentric half ball valve Product introduction

PQ340F PQ340H Eccentric half ball valve manufacturer, factory and supplier. PQ340F PQ340H Eccentric half ball valve is suitable for natural gas pipelines, eccentric half ball valve body is integrated, reduce leakage point, easy maintenance, advanced technology, high acceptance pressure, wide range of use. PQ340F PQ340H eccentric half ball valve pressure loss is small: fully open when the water loss is zero, the flow channel is completely smooth, and the medium will not deposit in the valve body cavity; High Material wear resistance: V-shaped opening between the ball crown and the metal seat with shear action, in the closing process, only in the z moment after the ball crown to the seat, no friction, and the seat made of wear-resistant nickel alloy, not easy to be scour and wear, so suitable for containing fiber, tiny solid material, pulp;

PQ340F PQ340H Eccentric half ball valve Product characteristics:

1. Switch is light: when opening, the spool is separated from the valve seat, without any contact, starting torque is less than the ball valve, flexible rotation;

2. Eccentric structure design, the use of eccentric - wedge CAM principle, close reliable, good sealing performance;

3. When the valve is closed, the wedge force can remove the scaling and adhesion on the sealing surface, with anti-scarring function.

PQ340F PQ340H Eccentric half ball valve Technical parameter:

1. Caliber DN40~DN1400

2. Pressure: PN6~PN64

3. Material: Ductile iron, WCB, CF8M, CF8(304), CF8M(316), CF3(304L), CF3M(316L), etc

4. Sealing surface: surfacing carbide, but also according to customer requirements valve disc or inner cavity spraying treatment

5. Connection mode: flange, clamp, welding

6. Operation: worm gear transmission, pneumatic, electric, hydraulic and other actuator optional
