Product Name: Bellows Globe Valve
Place of Origin: China
Features:
1) Nominal pressure: ANSI 150~800LB, JIS 10~20K, DIN
2) Size: 1/2" ~ 40"
3) Material: WCB 304 316 316L
4) Bellows welded to the stem parts and connecting pad provide a continuous metallic barrier between the process fluid and the atmosphere to achieve zero emissions
5) For added security there is also a stuffing box above the bellows for secondary sealing
6) The metal bellows are hydroformed multi walled structure which ensures them of 10000 full cycles at the maximum pressure for the valve
Advantages:
1) Double sealing design (bellows + stuffing box), if seal failed in bellows, emissions can be avoided for the packing in stuffing box, and this conforms to international standards
2) There is no leakage, so it can lower power expense and enhance equipment safety
3) Has longer life, decreases maintenance, cuts down operation cost
Use range:
1) It is designed specially for all kinds of dangerous, corrosive, flammable, pyrophoric and poisonous media such as VOC'S, HLG, and HAP
2) It is commonly used in industries like petrochemicals, chemical fiber textile, plastic textile, plastic papermaking, electric power steel smelting, printing rubber and food process
Packing: Wooden case
We can supply a wide range of butterfly valves, gate valves, globe valves, check valves, ball valves, relief valves, Strainers, hydraulic control valves, and pressure reducing valves.
Ningbo Valve Factory was founded as a valve manufacturer in 1959, Geographically, it is located in Ningbo, a seaport at the Delta area of Yangtze River, East China Sea. It takes us around 15 minutes by flight or 3 hours by bus from Shanghai to Ningbo. Company now covers an area over 30, 000 square meters and there are around 250 people at work.
Valve production and design
For decades we have been exploring our own valve engineering and learning other new techniques and designs in use we discovered all over the world, so far, we have succeeded a lot, some valves manufactured in our company have already equaled even exceeded the technical standard in western industrialized countries. To make sure product quality and delivery, we give tight control to the whole valve production from material selection, primary processing such as forging and casting, heat treatment, forming and so forth to final finishing processes.
How are we working with overseas customers?
We are committed to supply outstanding and professional services directly to intended customers all around the world, to delight our customers through our promise to continuous improvement in the design, engineering, and manufacture of products that set the standard for quality and value, we let partner gain from trade with NVF in the long run.
1. We are producing mechanical valves according to CAD or real sample provided by customers.
2. We design mechanical valves for customers who are able to tell us the specific application of the valves or standard that the valve should follow.
3. Selecting those valve carried in this showroom or on our website.
