The Introduction of ProductsZMAN pneumatic high temperature double seat control valve
A, ZMAN pneumatic membrane temperature regulation seat valve Overview ZMAN pneumatic film high temperature double-seat control valve is composed of multi-spring pneumatic film actuator and straight-through double-guided single-seat and double-seat valve. It has compact structure, light weight, sensitive action, small pressure drop loss, large valve capacity, and flow rate. Accurate characteristics. Equipped with electric-pneumatic valve positioning or pneumatic valve positioner, it can realize automatic adjustment and control of the fluid medium of the process pipeline. It is widely used to accurately control the process parameters of gas, liquid, steam and other media such as pressure, flow, temperature , Liquid level and other parameters are kept at the given value.Work 26 for M motion.

ZMAP, ZMAN type pneumatic single-seat and double-seat control valves (pneumatic film single-seat control valve, pneumatic film double-seat control valve) are the executive units of the instrument in the automation control system. Air is the driving force, accepting the 0-10mA DC or 4-20mA DC current signal input by the control system, and the regulator converts the compressed air into the air source pressure signal input and output, which can realize split-range control (segment amplitude signal) to change The valve opening displacement can achieve precise adjustment and control of the process parameters of the fluid medium
. ZMAP, ZMAN type pneumatic single-seat and double-seat control valves (pneumatic film single-seat control valve, pneumatic film double-seat control valve) can be divided according to the action mode; positive action: air-closed-normally open (when the signal pressure increases The valve position moves downwards), "Type B"
3.ZMAP, ZMAN type pneumatic single-seat and double-seat control valves (pneumatic film single-seat control valve, pneumatic film double-seat control valve) can be divided according to the mode of action; reaction: air-opening-normally closed (when the signal pressure increases, the valve Position shift upward), "K-type"
4. The ZMAP type pneumatic single-seat control valve is a straight-through single-seat cast spherical valve with a single-seat plunger type spool. It is suitable for working occasions where leakage is small and the pressure difference between the front and the valve is not large.
5. ZMAN type pneumatic double-seat regulating valve is a straight-through double-seat cast spherical valve with a double-seat plunger valve core, which is suitable for large pressure difference, large flow and not very clean medium and occasions where leakage requirements are not strict.
6. ZMAP type pneumatic single-seat control valve is a straight-through low flow resistance single-seat upper and lower double-guide structure. It has only one valve seat and one plunger-shaped valve core, which has good sealing performance and is suitable for strict medium leakage and adjustment accuracy. However, due to the valve structure, the unbalanced force of the upper and lower valve stems is relatively large, especially when the nominal diameter is large. Therefore, the valve is only suitable for occasions where the working pressure difference is small.
7. The ZMAN type pneumatic double-seat control valve is a straight-through low flow resistance double-seat upper and lower double-guide structure. The valve core is stable and reliable during the displacement process. The double-seat valve body consists of two valve core valve seats, and the fluid medium passes through the upper and lower valves. The core valve seat flows out, which has a large flow rate, a large allowable pressure difference, and a small unbalanced force. It is a double-seat valve with a balanced structure.
8. By changing the design of the spool shape; different spool shapes will get different flow characteristics: equal percentage (logarithmic), linearity.
This series of products are widely used in the automatic adjustment and remote control of industrial production processes such as chemical industry, petroleum, metallurgy, power station, light textile, papermaking and pharmacy.
There are standard type, adjustable cut-off type, bellows sealed type, jacket insulation type and other varieties. The product pressure grade is PN1.6 4.0 6.4MPa; the nominal diameter is DN20~300mm; the applicable fluid temperature is -60~+450ºC; according to the temperature, different valve covers can be divided into normal temperature type, high temperature type and low temperature type.With heat ZC letter thin key device 6, 8 wrap service 5 electric a2 valve seafood
From the beginning, the membrane is 8 more seats, high and 0 low, and I cut off the superior and thin-birth surgery 1m24 Three, ZMAN pneumatic film high temperature double-seat control valve actuatorThe ZHA/B multi-spring pneumatic film actuator is composed of diaphragm, compression spring, tray, push rod, bracket, shaft sleeve, diaphragm cover and other main parts. It is a new type of pneumatic membrane actuator designed and developed to solve the problems of the old ZMA/B single-spring pneumatic membrane actuator, such as large size, bulky, and unreliable deep corrugated diaphragm. Its membrane cover plate, restricting parts and other parts are all made of steel plate. Stamping. The shape of the diaphragm is more complicated, and a special pressing process is adopted to make the blasting strength above 22kg/cm2. The multi-spring form improves the manufacturability of spring manufacturing and facilitates the assembly of different spring ranges. The zero-adjustable function improves the linearity accuracy. Surface treatment adopts epoxy electrostatic powder without spraying, which has high fastness and corrosion resistance. It has the advantages of uniform force, good stability, small size and light weight. Compressed air is used as the energy source to receive the air source pressure signal input by the electro-pneumatic valve positioner or solenoid valve. This pressure acts on the diaphragm of the membrane chamber to generate thrust to compress the spring assembly and make the push rod move. When the push rod and the spring When the reaction force generated after the group is compressed is balanced, the valve stem is stabilized on the corresponding stroke. According to the force balance principle, the stroke size is proportional to the pressure signal input size, so as to achieve accurate positioning of the valve spool..Strict 1 titanium set 1053 control, grid 6, miscellaneous spray 2 seat cleaning 1
