Configuration Options:

Name of Parts

Material

Advantages/Disadvantages

Valve Body

Bronze

Bronze has the characteristics of low melting point, high hardness, strong plasticity, wear resistance, corrosion resistance, bright color, etc.

Cast iron

The tensile strength, ductility and toughness of cast iron are lower than those of carbon steel. Lower price than bronze and stainless steel

Carbon Steel

Low strength, low hardness, good plasticity and good weldability.

Stainless Steel

High corrosion resistance makes it usable in harsh environments. It is fire and heat resistant, resists scaling and maintains strength at high temperatures.

Valve Disc

Stainless Steel

Stainless steel has a strong ability to resist tension, wear and corrosion. Stainless steel is much stronger than copper in material. Stainless steel will not produce corrosion, pitting, rust or wear and high temperature resistance.

Aluminum Bronze

It has high strength and good wear resistance. It is used for high-strength screws, nuts, copper sleeves, sealing rings, etc., and wear-resistant parts. The most prominent feature is its good wear resistance.

Valve Seat

NBR

Applicable medium 0-80℃ oil class

EPDM

Suitable medium -20-120℃ water, steam, etc

PTFE

Applicable to corrosive media below 200℃

Hard alloy

Suitable for high temperature and high pressure environment

Valve Stem

Stainless Steel

Key advantages include its high corrosion resistance, making it usable in harsh environments. It is fire and heat resistant, resists scaling and maintains strength at high temperatures.

Handle

Cast Iron

Cost less than bronze

Result

Reduce body thickness to reduce costs

At high temperature and high pressure or during operation, the thin wall is easy to rupture or leak the valve, causing a safety hazard.

Ensure that the thickness of the valve body meets the standard requirements, and there is no fraudulent behavior

Use with confidence, meet user needs, and the product has a long service life

To reduce costs, refurbish old valves to act as new valves and re-sell

Refurbished valves are easy to cause shell cracking and leakage, and in severe cases, oil and gas pipelines will explode.

According to customer requirements to manufacture new valves, never shoddy.

Meet the hardness and precision requirements of standard valves,

Ensure the quality of the valve and ensure the normal operation of the equipment.

Valve seat is made of waste rubber

Not durable and waste of resources, once the valve seat is worn and damaged, the entire valve is considered waste

The rubber valve seat is made of a new type of super wear-resistant rubber, and can be reused

The rubber material is super wear-resistant and can be reused, and the valve can be used for a longer time

The valve seat, valve stem, and valve disc are all fixed configurations, which cannot be disassembled and assembled individually, and cannot be replaced with individual parts.

If a part is damaged, it can only be replaced as a whole, wasting resources and increasing costs

Seat, stem and disc are standard parts

Replacing accessories is simple and easy, saving time and effort. Not only reduce costs, but also save resources for the country
