Globe Valve

      CHAODA group专业研制生产Globe Valve等 valve products, CHAODA生产的Globe Valve has the features of Good sealing, reliable, safety and long life span.

     Globe Valve是指关闭件(阀瓣)沿阀座中心线移动的阀门。根据阀瓣的这种移动形式,阀座通口的变化是与阀瓣行程成正比例关系。由于手动Globe Valve的阀杆开启或关闭行程相对较短,而且具有非常可靠的切断功能,又由于阀座通口的变化与阀瓣的行程成正比例关系,非常适合于对流量的调节。因此,这种 Globe Valve非常适合作为切断或调节以及节流使用。

CHAODA Valves Group is specialized in manufacturing Globe valve with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc. 

As the globe valve has a relative short opening and closing distance with very reliable cutting off function. Also the passage size of seat is changing to a directly proportional with the traveling distance of disc. All above features make the globe valve very suitable for cutting off, connecting or regualting purpose.

     CHAODA GROUP WENZHOU E-BUSINESS CO.,LTD. is a wholly owned subsidiary of CHAODA VALVES GROUP CO.,LTD.With  Chaoda valves group(CHAODA group”) quality management and safety system(Get the approvals of ISO9001,ISO14001,OHSAS18001, API6D, CE/PED, API607,API6FA, ISO15848-1, TS and API600 gate valve certified),top level developing team(Provincial Key Enterprise research Institute,Provincial Key Enterprise Technology  Innovative Group, Provincial Enterprise Technology Center),advanced machining equipment, well chemical analyst and inspection equipment(Optical Spectrometer, Helium low emission tester, High & Low temperature performance equipment and etc)we could provide our clients with perfect products and satisfied service.

Globe Valve product description

     Globe Valve适用于Class150~Class1500,PN16~PN160的各种管路上,用于截断或接通管路中的介质。选用不同的材质,CHAODA group的Globe Valve可分别适用于水,蒸汽,油品,硝酸,醋酸,氧化性介质,尿素等多种介质。Globe Valve的驱动方式为手动,蜗轮传动,气动或电动。Globe Valve一般采用法兰连接,也可采用对焊连接。

Globe valves(Generally flanged connection, but Butt-welding optional) are suitable for using on various kinds of pipeline from PN16 To PN160, Class150 To Class1500 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/bevel gear/pneumatic or electric actuators could be chosen by needs. 

     Globe Valve属于强制密封式阀门,所以在阀门关闭时,必须向阀瓣施加压力,以强制密封面不泄漏。

Globe valve is the type of valve needing forced sealing. So external force should be given for the disc when closes to have a good sealing.

     CHAODA GROUP WENZHOU E-BUSINESS CO.,LTD.is wholly owned subsidiary by Chaoda Group,Professional sales CHAODA group products,CHAODA valve products。CHAODA valves won the reputations of Zhejiang Famous Trademark,Zhejiang Famous Brand,Zhejiang Famous Exporting Brand and also enjoys prizes of 101 National Patent。

Globe Valve product features

     The features of globe valve:Bolted Bonnet; Outside Screw and Yoke; Rising stems; Metallic seating surfaces.

     Body and Bonnet Connection:The body and bonnet of Class150~Class900 globe valves are usually bolted bonnet design. And the The body and bonnet of Class150~Class900 globe valves are usually bolted bonnet design. And the Class1500~Class2500 globe valves are usually of pressurized seal design.

     Gasket of Cover Flange:Stainless steel + flexible graphite wounded gasket is used for Class150 and Class300 globe valve. Stainless steel + flexible graphite wounded gasket is used for Class600, and ring joint gasket is also optional for Class600. Ring joint gasket is used for Class900 globe valve. Pressurized seal design is used for Class 1500~Class2500 globe valve.

     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 can be adopted for enhancing the durability and reliability of the packing seal.

     Back Seating Design:All our globe valves have the back seating design. In most cases, the carbon steel globe valve is fitted with a renewable back seat. For stainless steel globe valve, the back seat is machined directly in the bonnet or is machined after welding. When the globe valve is at fully open position, the sealing of the back seat can be very reliable. However, as per the requirement of API, it is not advisable to add or change packing by the mean of back seating when the valve is pressure containing.

     Seat:For carbon steel globe valve, the seat is usually forged steel. The sealing surface of the seat is spray welded with hard alloy specified by the customer. Renewable threaded seat is used for NPS≤10 globe valve, and welded on seat can be also optional if being requested by the customer. Welded on seat is used for NPS≥12 carbon steel globe valves. For stainless steel globe valve, integral seat is usually adopted, or to weld hard alloy directly integrally. Threaded or welded on seat is also optional for stainless steel globe valve if being requested by the customer.

     Stem Design:The stem is of integral forged design. The minimum diameter of the stem shall per the standard requirement. 

     Stem Nut:Usually, the stem nut is made of ASTM A439 D2. It is also can be made of copper ally if being requested by the customer. For large sized globe valve, rolling bearing is fitted at the two sides of stem nut in order to minimize the open and close torque of the globe valve.

     Special Globe Valve:Besides the common globe valves, Chaoda Company also makes cryogenic globe valve, bellow sealed globe valve, Jacketed globe valve, etc.

      CHAODA Globe Valve has the features of Good sealing, reliable, safety and long life span.

      CHAODA VALVES GROUP CO.,LTD. launched its quality management and safety system as ISO9001,ISO14001,OHSAS18001, API6D, CE/PED, API607,API6FA, ISO15848-1 TS and API 600.
