Zhengmao Valve National Standard Gate Valve: Compliant and Reliable Choice for Industrial Sites
First, let's look at the solid parameters: the valve body is made of 20# steel or 304 stainless steel, which can be selected according to working conditions. The nominal diameter ranges from DN50 to DN600, and the nominal pressure can withstand 1.6MPa to 6.4MPa. Under normal temperature, the sealing test pressure directly reaches 1.1 times the nominal pressure. Whether it's water, oil or neutral gas, it shuts tightly without leakage. Unlike some non-standard valves that go wrong after a while, our national standard valve comes with complete inspection reports and material certificates, making project acceptance worry-free and hassle-free.
Then talk about the advantages in use: the gate is integrally forged, with a precision-ground surface, so it opens and closes smoothly without jamming, and the handwheel is easy to turn-workers all praise it for being easy to operate. The valve stem adopts chrome plating technology, which is rust-proof and wear-resistant. Even if it's exposed to the open air or in a humid environment for a long time, it won't rust and get stuck easily. If the production line needs to cut off fluid quickly, use it together with our floating ball valve-one is responsible for stable adjustment, and the other for emergency shut-off, making the whole system efficient and safe.
Now you can see it in municipal water supply, chemical pipelines, and process pipelines in power plants and oil refineries. For example, in chemical workshops, it can accurately control the flow when transporting raw materials; during the maintenance of municipal pipe networks, it shuts off without dripping, not affecting water use in surrounding areas. The most reassuring part is the after-sales service-this national standard gate valve comes with a one-year warranty. Whether you need technical guidance during installation or have minor problems later, just make a call, and someone will respond within 24 hours. Spare parts replacement is also fast, so production won't be delayed.
