API Gate Valves
API Gate Valve developed by Chaoda has following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc. Pressure retaining component is all produced with precision casting, and malleable iron is used for the handwheel to match the stem so as to have a easy operation of valve. There is a clear sign of "Open" & "Closed" on valve's handwheel.
API Casting Gate valve is widely used on pipeline in industries such as steel, metallurgy, chemical where needing oxygen for its advantages of reliable sealing, high hardness, wear-resistance, high temperature resistance, corrosion resistance, long life span and etc. According to different types of disc, it could be divided into Wedge gate valve & Parallel gate valve. Wedge gate valve could be: single disc solid wedge gate valve, double disc wedge gate valve and flexible wedge gate valve; Parallel gate valve could be single disc or double disc type. However, if we classify the valve by the different positions of stem thread, then it could be rising stem and non-rising stem type gate valve. Manual/bevel gear/pneumatic or electric actuators could be chosen by needs

API Gate Valve product features
Design of Disc:Gate Valves with NPS≥2 are of flexible wedge gate; Gate valves with NPS < 2 are of solid wedge gate.
Body and Bonnet Connection:The body and bonnet of Class 150~Class 900 gate valves are usually bolted bonnet desing. And Class 1500~Class 2500 gate valves are usually of pressurized seal design.
Gasket of Cover Flange:Carbon steel or stainless steel + flexible graphite combined gasket is used for Class 150 gate valve; Stainless steel + flexible graphite wounded gasket is used for Class 300 gate valve; Stainless steel + flexible graphite wounded gasket is used for Class 600 gate valve, and ring joint gasket is also optional for Class 600 gate valve; Ring Joint gasket is used for Class 900 gate valve; Pressurized seal design is used for Class 1500~Class 2500 gate valve.
Actuation:Hand wheel or gear box is usually used for gate valve actuation. Chain wheel and electric actuator can be also used for gate valve actuation if being requested by the customers.
Packing Seal:Molded flexible graphite is used for packing material. PTFE or combined packing material can be also used if being requested by the customer. The internal surface of the stuffing box, of which area is contacted with the packing, is of excellent finish (Ra 3.2 |m). The stem surface, contacting with the packing, should be rolled and pressed after being precisely machined, so as to reach to the high finish and compactness (Ra 0.8 |m ) and ensure the reliable tightness of the stem area.
Belleville Spring Loaded Packing Impacting System:If being requested by the customer, the Belleville spring loaded packing impacting system can be adopted for enhancing the durability and reliability of the packing seal.
