Also called high differential pressure regulator, which is a novel structure of the control valve . STC water pump minimum flow recirculation control valve is an air-conditioned multi-stage throttling control valve, the valve is mainly used for large generating units on the water supply system is to prevent boiler feed water vaporization of the important equipment, but also the power plant key control valve one.
Cascade minimum flow recirculation control valve has the following advantages:
1. Step-down fluid step by step, the direction of the fluid constantly changing, increasing the flow resistance to prevent the flow of liquid pressure to 24MPa does not appear cavitation.
2. Valve spool 5 throttling, valve seat sealing surface to set a throttle plate, STC water pump minimum flow recirculation regulating valve has a cascade structure and two types of labyrinth structure. The fluid passes through tortuous passages with the purpose of consuming fluid energy, reducing flow rate and preventing liquid cavitation.
To improve the fluid flow state, control the flow rate of about 30m / S.
3. Throttling surface and the sealing surface separate, spool, spool sleeve and throttle plate by the hardening treatment, the surface hardness of about HRC70, close tight, long life.
4. The valve core surface has a large gap, even if the liquid contains 2 ~ 3mm slag and other solid particles, the valve core will not be stuck, flexible action.
Flat Bags on Roll is commonly used in every industry, such as electronically products, accessories,household, cosmetic, commodity, stationery, toy, fruits,vegetable and food products etc. Specially in packing of fresh fruits, fresh vegetables, meat, seafood, cakes,chocolates, candy, cookies,biscuits and so on.
The bags could be in big roll for industry and supermarket or in small or for household.
