Ammonia bellows globe valve

AWJ41F-25C、AWJ41F-40CAmmonia bellows globe valveIt is an extended bellows globe valve with a double sealing design for the stem position, which provides more reliable sealing performance than ordinary globe valves. The service life of the bellows ammonia shut-off valve largely depends on its core component - the bellows. The extended design greatly improves the fatigue resistance and service life of the bellows ammonia shut-off valve, making it have a significant and unique advantage in harsh working conditions.

Product advantages:

1. Valve stem: Thickening the valve stem can increase its wear resistance, especially suitable for reactor mixing systems and high-pressure storage tank equipment.

2. Bellows: Extended, multi walled, anti torsion, long-life corrugated pipes, capable of breaking the opening and closing life of ordinary domestic corrugated pipes, with a maximum of 10000 cycles. German imported corrugated pipes are selected for harsh working conditions.

3. 360 degree free turntable: It can clean impurities and carry fluids to close different surfaces of the valve seat, while not sending vibrations to the valve stem.

4. Corrugated pipe protective space design: The corrugated pipe is sealed in a closed space, unaffected by the medium, pressure, and temperature.

5. The reverse sealing design is equipped with a travel limiter and a bellows anti vibration device in the open position.

6. The valve body adopts German coated sand casting technology, which greatly improves the surface smoothness and mechanical properties of the valve body, reduces the occurrence of pores, sand holes, and cracks, and enhances the tensile strength of the casting.

7. According to the working conditions, other valve disc designs (throttle valve disc, regulating valve disc) can be provided
