Product overview

Pneumatic gate valve Z641H-16C-DN200 is a right Angle rotating structure, which can be used with the valve positioner to achieve proportional adjustment. V-type spool is suitable for various adjustment occasions, with large rated flow coefficient, large adjustable ratio, good sealing effect, zero sensitivity adjustment performance, small volume, can be vertically installed. Suitable for controlling gas, steam, liquid and other medium


Nominal diameter and nominal pressure

Nominal diameter: DN200, indicating the standard inner diameter size of the valve.

Nominal pressure: PN16, indicating the maximum allowable working pressure of the valve at a certain temperature 

Connection mode and structure form

Connection mode: Flange RF, suitable for all kinds of pipe system connection.

Structure: open rod wedge type, piston type cylinder control switch, making the operation more convenient 

Body material and sealing performance

Valve body material

The body material of Z641H-16C-DN200 pneumatic gate valve adopts WCB/13Cr double acting design. Among them, WCB represents carbon steel, with good mechanical properties and processing properties; 13Cr is a kind of stainless steel containing chromium, which improves the corrosion resistance of the valve body, especially suitable for use in harsh environments such as petroleum and chemical industry.


Sealing performance

Pneumatic gate valve Z641H-16C-DN200 adopts double cylinder structure, and its lifting force is doubled compared with single cylinder pneumatic gate valve. This fundamentally solves the problem that some valve bodies of single-cylinder pneumatic gate valves are dead and cannot be opened. Moreover, because the valve has a buffer mechanism, it can effectively slow down and light the wear of the valve plate sealing surface and the valve body sealing surface caused by the downward impact of the piston when the valve is closed, and at the same time, it can avoid the phenomenon of the gate dead


Main technical parameters

Model: Z641H-16C

Nominal pressure: 16MPa

Working temperature: ≤350℃ (carbon steel)

Applicable media: water, steam, oil and other non-corrosive medium


Pneumatic gate valve Z641H-16C-DN200 is a high-performance pipeline control equipment, its design combines the advantages of WCB (cast steel) and 13Cr (13% chromium steel) two high-quality materials, as well as the efficient drive mechanism of double acting pneumatic head, so that it has been widely used in many industrial fields. The following are the main uses of the pneumatic gate valve:


Industrial application

Chemical industry

In the chemical production process, it is often necessary to deal with corrosive, high temperature or high pressure media. The body material WCB and 13Cr of Z641H-16C pneumatic gate valve can resist corrosion and wear under these harsh conditions to ensure long-term stable operation of the valve 1.


Oil and gas

During the extraction, transportation and processing of oil and gas, reliable valves are needed to control the flow of fluids. The dual acting pneumatic head of the pneumatic gate valve provides fast and precise switching operation for high pressure and high flow applications2.


Electric power industry

In power stations, pneumatic gate valves are used to control the flow of cooling water, steam and other critical fluids. Its resistance to high temperature and pressure, as well as reliable sealing performance, is essential to ensure the safe operation of the equipment 


Pharmaceutical and food industries

In these industries, hygiene and purity are highly required. While WCB and 13Cr May not be the preferred sanitary grade materials, their durability and reliability still make this valve suitable for some applications where products are not directly in contact, such as plant utility system


Special application

Ocean engineering

In the Marine environment, equipment needs to withstand challenges such as salt spray corrosion and high humidity. The corrosion resistance of the Z641H-16C pneumatic gate valve makes it an ideal choice for offshore platforms and Marine piping systems


Mining industry

In mining operations, valves need to handle slurry and pulp containing solid particles. The pneumatic gate valve's robust construction and wear-resistant material are designed to handle these harsh conditions
