Product Description

Hastelloy pneumatic valve is using compressed air as power source, using the cylinder as the actuator and valve positioner, aid, converter, electromagnetic valve, the valve, gas filter attachment to drive the valve, switch or proportional regulator, a control signal receiving industrial automation control system to adjust the pipeline to complete the medium: flow, pressure, temperature, level and other various process parameters. Hastelloy pneumatic control valve is characterized by simple, rapid response, and intrinsically safe, no need to re take the explosion-proof measures.
Use and characteristics:
A, Hastelloy alloy pneumatic applications and characteristics of valve structure of a right angle turn, it is supporting the use of valve positioner, the ratio can be adjusted; type V valve adjustment for a variety of occasions, with a rated flow coefficient, adjustable ratio, good sealing effect, regulating sensitive performance, small size, vertical horizontal installation. Applicable to control of gas, steam, liquids and other media.
B, characteristic: the structure of a right angle turn, by the V type valve, pneumatic actuator, positioner and other accessories; there is a nearly 100 than the inherent flow characteristics; dual bearing structure, the starting torque is small, with excellent sensitivity and speed sensors; shear capacity of strong.
C, pneumatic piston executing agency for the use of compressed air power source, through the piston's movement led to a 90 degree turn, to enable the automatic gate valve. Its components are: adjustment bolt, the executive body box, crankshaft, cylinder block, cylinder, piston, connecting rod shaft, cardan shaft.
D, Hastelloy alloy pneumatic control valve works: Hastelloy pneumatic valve by the implementing agencies and regulatory agencies. Executing agency is the thrust control valve components, which according to the control signal pressure to produce the thrust, push the adjustment mechanism of action. The valve body is Hastelloy pneumatic control valve adjustment parts, it has a direct contact with the media regulator, regulating the flow of the fluid.
Installation principle:
(1) Hastelloy pneumatic control valve installation position, from the ground requires a certain height, the valve is to have a certain space, so that valve disassembly and repair. For the valve with pneumatic valve positioner and the handwheel, must ensure that the operation, observation and convenient adjustment.
(2) regulating valve should be installed in horizontal pipelines, and up and down with the pipe vertical, generally under the valve to be supported, to ensure stable and reliable. For special occasions, the level control valve installed in a vertical pipe when necessary, the valve should also be supported (except for small caliber valve). When installing, avoid to the control valve to bring additional stress).
(3) the working environment temperature regulating valve in the (30 ~ + 60) relative humidity of not more than 95% 95%, relative humidity of not more than 95%.
(4) regulating valve before and after the position should be straight pipe, pipe length not less than 10 times the diameter (10D), in order to avoid the valve pipe is too short and flow characteristics.
(5) the caliber and the process pipeline valve are not the same, should adopt different diameter pipe connection. In the small caliber valve installation, by threaded connection. The flow direction arrow on the body should be consistent with the direction of fluid.
(6) to set the bypass pipe. The purpose is to facilitate the switch or manual operation, can not shut down for maintenance of the regulating valve.
(7) control valve in the prior to the installation of complete removal of foreign bodies in the pipe, such as dirt, welding slag etc..
Use the matters needing attention:
1, the valve should be stored in dry room, two ends must be blocked pathway. No heap storage
2, the long-term storage of the valve should be checked regularly, remove dirt, the movement part and the processed surface should be coated with anti rust oil, prevent rust.
3, the valve should be installed in horizontal pipelines, the required vertical installation. Stem upward.
4, the required according to the arrow indicating the direction of media flow to install.
