Briefly describes the pneumatic brake pneumatic valve product advantages, and its model

outlining the pneumatic brake valve product advantages, and its model? Pneumatic brake valve although is simple to use, mainly by medium pressure seal, but in the process of work, should strictly comply with the instructions on the operation instruction. Most brake pneumatic valve is sealed with mandatory, so once when the pneumatic valve closing, is the need to rely on outside force forced the ram pressure to the pneumatic valve seat, which can ensure the sealing surface sealing. Pneumatic brake valve is there are two types, one is a pneumatic brake valve type, another kind is spring return to perform
pneumatic brake valve model and its advantage of products:
. Pneumatic brake valve type - Spring return:
choose spring return actuators, should according to the need of the torque value, to increase the TVC %, the spring reset torsion spring torque column in the table, looking for a right than to TVC some torque value, according to the air pressure, can find accurate GT single-acting actuator models ( This value should be than spring torque) 。 For example: control needs a Nm torque of pneumatic valves, for the sake of safety, increase the % for Nm torque, within the column marked with the spring torque GT + ° K this line to find the value of the Nm along the bank, to the right on the marked. MPa column to find the Nm of torque value, the actuator model for GT + °, K, air pressure is required for. MPa。
. Pneumatic brake valve type - Double-acting pneumatic actuators:
choose double-acting actuators, double-acting pneumatic actuator torque table lookup, according to the need of the torque value, and then increase the TVC %, and then according to the gas source of working pressure and torque table lookup, the accurate GT models. Control, for example, a need to Nm torque of pneumatic valve, considering safety factors increase % to Nm, can choose GT x type of actuator ( Throughout the year. MPa provides Nm of torque) : or select GT x type actuator ( Throughout the year. The MPa provides Nm of torque. （ According to the hulunbuir news)
