Straight trip valve stem Marine valve movement up and down, packing pressure a bit, it will wrapped the stem very tight, initiation of the larger back to the poor. Q: shallow talk straight travel regulating valve stem finer comprised a: straight travel electric regulating Industrial Valves is shut execution units of industrial semi-automated processes stem instrument. To this end, the valve stem default fine small, packing and commonly used small friction coefficient of ptfe packing, so that detract from back to the poor, but the problem is sent stem thin, is easy to bend, packing and short duration of survival. Straight travel regulator valve stem is comprised of fine: it involves a simple mechanical principle: sliding friction, less bone friction. Regulating valve the flow of special properties are: linear special properties, such as percentage of special properties and parabolic special nature of the three. Solve this problem, the best way is to use brigade rotary valve stem, namely quarter-turn class regulating valve, its stem than straight travel stem thick 2 ~ 3 times, and the survival of the straight-line long its packing, stem good stiffness, packing live longer, but the friction torque is small, poor little back. Straight for the installation of office travel electric regulator is the most fitting for piston top at the bottom of the level line, its structure by the electric actuator and valve combination period through mechanical assembly and adjust the electric control valve installation period. 。 Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
