Bronze Gate Valve

Bronze Gate Valve

Structural features:

Reasonable material selection, in line with domestic and foreign standards, reasonable structure, beautiful appearance.

After quenching and surface nitriding treatment, the valve stem has good corrosion resistance and scratch resistance.

It can match with all kinds of flange pipe standards and sealing surface patterns to meet all kinds of engineering needs and user requirements.

Body material is complete, packing and gasket can be matched according to the actual working conditions and reasonable requirements of users, suitable for all kinds of pressure, temperature and medium conditions.

Consequence

Our Factory

Use effect

In order to reduce the cost, omit raw materials and reduce the internal quality, resulting in the thin wall of the valve body, which accounts for the theme of the valve

Leaving potential safety hazards, the thin wall is easy to fracture or leak the valve under high temperature and high pressure or in operation

It is processed in strict accordance with the standard, with uniform thickness and material

It is safe to use, meets the needs of users, and has a long service life

The valve cover has poor manufacturing quality, uneven thickness and uneven material

The valve cover is prone to damage, sand holes, corrosion or aging

It is processed in strict accordance with the standard, with uniform thickness and material

The valve cover is of good quality, not easy to produce pores, and the product has a long service life

Refurbished valves, some operators sell the used valves for the second time after repainting, which brings serious safety hazards to the project quality

The refurbished valve is easy to cause shell cracking, and the phenomena of running, emitting, dripping and leakage will occur, which will cause oil and gas pipeline explosion in serious cases

Make new valves in strict accordance with the material requirements of customers, and never substitute inferior products for good ones

Meet the hardness and accuracy requirements of standard valves, ensure the quality of valves and ensure the normal operation of equipment

Flange manufacturing quality is poor, with cracks, pores, insufficient thickness and other problems

As a result, the valve is wear-resistant and the pressure bearing is poor. The valve is prone to quality problems and has a short service life

Use materials in strict accordance with national standards

The valve has good wear resistance and pressure bearing performance and is not easy to be damaged

Replace copper valve stem with iron plated valve stem

The performance of substitute materials is unstable, resulting in the decline of valve quality

Select materials in strict accordance with user requirements

High safety factor, reasonable structure and long service life of products
