1. The amount of urea should not exceed 1/3 of the total nitrogen requirement, and should not exceed 1% of the dry matter of the diet. 2. Because urea has good hygroscopicity, it is easy to be decomposed into ammonia. It can not be fed alone or dissolved in water. It can't drink water for 2 hours after feeding. 3. Urea has poor palatability. It is best to add it to the mixed concentrate to make urea or mineral feed bricks with starch feed, salt and other mineral feeds for cattle to eat and reduce the intake rate. 4. When urea is added to the feed, the bean cake cannot be fed at the same time. Because the urea bean is contained in the raw bean cake, the decomposition of urea is accelerated in the presence of water, causing loss.
Globe Valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.
Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services. Angle Valves, Angle Globe Valves, Brass Angle Valve, Zinc Angle Valve ZHEJIANG KINGSIR VALVE CO., LTD. , https://www.kingsir-valves.com
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose
