Lift Check Valve

Lift Check Valve

Application

The valve is used for shipbuilding, ship repair and oil platform with high quality.

Configuration Options

Name of Parts	Material	Advantages/Disadvantages
Valve Body	Bronze	Bronze has good casting, friction reduction and mechanical properties
	Brass	Brass has low pressure resistance and is easy to rust. The price is lower than bronze.
Valve Bonnet	Bronze	Good castability, wear and corrosion resistance and stable chemical properties
	Brass	It has the advantages of high strength, toughness, good antifriction, high corrosion resistance in the atmosphere and sea water, but it has the tendency of corrosion and rupture
Valve Disc	Bronze	Bronze has excellent low temperature resistance, the price is a little more expensive than stainless steel, and the seawater resistance of bronze is better than that of stainless steel
	Brass	Good mechanical properties, good plasticity in hot state, good plasticity in cold state, good machinability, easy fiber welding and welding, corrosion resistance, but easy to produce corrosion cracking, and cheap
Gasket	Non-asbestos	It has very good water tightness, air tightness, and fuel tightness, good mechanical properties, oil resistance, temperature resistance, and pressure resistance.

Specific Difference Between Us and Other Suppliers

Comparison
Product Picture of other low quality supplier		Product Picture of our factory
Other low quality supplier	Consequence	Our Factory	Consequence
In order to reduce costs, omit raw materials and reduce internal quality, resulting in the thin wall of the valve body that occupies the main body of the valve.	Leaving a safety hazard, the thin wall is easy to break or leak the valve at high temperature and high pressure or during operation.	Strictly in accordance with the standard processing, uniform thickness, and material	Use with confidence, meet user needs, and the product has a long service life
Poor manufacturing quality of valve cover, uneven thickness, uneven material	Bonnets are prone to breakage, blisters, corrosion or aging problems	Strictly in accordance with the standard processing, uniform thickness, and material	The quality of the valve cover is good, it is not easy to generate air holes, and the product has a long service life.
Refurbished valves, some operators sell the waste valves for the second time after repainting, which brings serious safety hazards to the quality of the project	Refurbished valves are easy to cause the shell to crack, and the phenomenon of running, running, dripping and leaking occurs, and in severe cases, the 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.
The quality of flange manufacturing is poor, and there are problems such as cracks, pores, and insufficient thickness	the valve is not wear-resistant, the pressure bearing is poor, the valve is prone to quality problems, and the service life is short.	Select materials in strict accordance with national standards	The valve is wear-resistant, has good pressure-bearing performance, and is not easy to be damaged.
