Stainless steel fittings used in selected cases, must follow the model selection criteria of goods when choosing to pay attention to the type, the temperature of the fluid. Select appropriate type of fluid, temperature of the material and sealing material itself. On the basis of fluid, The right itself material, sealing material is not the same. For example, the joint is gas. Strongly recommend made of steel, is water, choose copper and 304 stainless steel. In the process of choosing auto rotary joint also need to be concerned with the liquid Pressure of work, please select the appropriate compressive properties of the joint fluid pressure, fluid of burden is also selected joint. Pneumatic amplifying device: installed in the gas supply to cylinder working pressure of the locator data signals, give a very large total flow to the actuator, to improve the speed of the gate. According to the 1:1 (data signal and export proportion). The key to use In pneumatic data signal transmission to the long distance (0-300 m), reduces transmission lag behind.
Pneumatic: the position control valve is mainly for air stainless steel needle valve pressure to carry out the interlock of the actual operation, when the work is less than the air pressure pneumatic pipeline emergency cut-off valve, keep gate valve parts before air common faults. When the air pressure to repair, at the same time to repair The pneumatic cylinder.
Air solution components: there are two parts and the joint parts, role is overdone, relieve pressure, welding smoke and dust. Proposed installation, to prevent the cylinder into the residue cause cylinder jammed.
Valve positioner: according to the proportion gather pneumatic ball valve must be installed, more to the pneumatic V type ball valve. Type 4-20 ma, want to consider whether take feedback derived data stainless steel tube fitting signal. Must explosion-proof type. There are universal, all smart.
Quick exhaust valve: accelerate the pneumatic ball valve power switch rate. Installed in the middle of the cylinder and solenoid valve, make the gas inside the cylinder is not through the electromagnetic valve, come out quickly. Pneumatic ball valve is used in intelligent automation control system of a kind of widespread pneumatic electric actuators. To manipulate data signal based on pneumatic actuators to move the ball valve power switch position, on a line of the power switch control or adjust the control.
Electromagnetic valve: double efficacy cylinder with stainless steel hydraulic fitting two general five-way solenoid valve or three five-way solenoid valve. Single-acting cylinder can match two the 3-way magnet valve (pos. Working voltage can be used DC24V, AC220V, etc. Take into account the explosion-proof type.
Limit switch: the effect is to make the electric actuator for the contact point of rotation transformation of data signals, export to control instrument, feedback the ball valve of the buttons on the spot. Common have a pedal, induction coil. Also need to consider the explosion-proof type.
Spindle organization: installed in the middle of the ball valve and cylinder, can be in air common failure to manual type power switch, make sure the system optimization, don't delay production.
