Cast Iron Angle Globe Valve

Cast Iron Angle Globe Valve

Introduction:

Cast iron angle globe valve refers to a valve in which the closing member (disc) moves along the centerline of the valve seat. According to this moving form of the valve disc, the change of the valve seat port is proportional to the valve disc stroke. Because the valve stem of this type of valve has a relatively short opening or closing stroke, and has a very reliable shut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for flow regulation.

Product drawings of other low-quality suppliers		Our factory manufactures products

Low quality product features	Consequence	Features of our products	Achieve results
1. Insufficient raw materials; 2. The processing method is not standard	The wall thickness is uneven, the material distribution is uneven, the valve body is easy to be damaged, and the service life is short	It is processed in strict accordance with the standard, with uniform wall thickness and material	The product has high safety factor and long service life
1. Made of iron and carbon steel; 2. Use the recovered scrap valve to repair and then sell it again;	The hardness and accuracy of the valve cannot meet the needs of use, and the shell is easy to crack, resulting in running, emitting, dripping and leakage, and even causing oil and gas pipeline explosion	Select high-quality materials according to customer needs, and make new products in strict accordance with standards	The hardness and accuracy of the valve meet the standard quality requirements to ensure the normal operation of the equipment
To improve profit margin, purchase cheap unqualified bolts	Unqualified valve bolts lead to safety hazards, which is easy to cause accidents	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	It leads to wear resistance and poor pressure bearing of the valve, and the valve is prone to quality problems, which makes short service life	Adopt standard bolts with quality assurance in strict accordance with customer requirements	Improve safety factor and prolong service life
In order to reduce the cost, cast iron valve core is used instead of bronze valve core	Cast iron valve core is easy to be corroded and damaged	Select standard materials in strict accordance with customer requirements	The product structure is reasonable and the safety factor is high
In order to reduce costs, ordinary round steel valves are used instead of stainless steel valves	1. The diameter of valve rod fails to meet the requirements; 2. The performance of alternative materials is unstable, without heat treatment, the quality can not meet the standard, and the service life is short	1. Made of stainless steel; 2. The diameter of valve rod meets the design requirements; 3. High temperature quenching and tempering heat treatment	The product has reasonable structure, high safety factor and long service life
