Basic surveying instrument error should be less than a quarter of basic error limits the check Industrial Valves. Pneumatic control valve is a stem simple, reaction is rapid, the essence safety of products, no extra to adopt explosion proof treatment method. Q: pneumatic - valve fixed schedule deviation requirements how to reduce the pressure? Answer: in order to guarantee the gas valve closed in place, demand will be 120 one hundred percent signal for actuator chamber, from 100 - one hundred percent 120 one hundred percent signal stem walk trip and norm the ratio of the trip, this is norm of deviation. Pneumatic control valve leak check quantity demand for 10 - try to media 50 ℃ cleaning gas ( Air or nitrogen) Or liquid ( Foreign oil or water) 。 。 If it's a bit of a basic error, then will be stipulated by the input signal is flat to secure local input actuator (in the direction shown by the increase/decrease Or locator) , exploration of the values, the actual 'signal - Trip 'relationship with the theory of relationship between Marine valve of each point can barely to calculate the maximum error is basic error. Inspection experience points should cover at least signal range 0 one hundred percent, 25, 50, one hundred percent and one hundred percent, 75 one hundred percent, 100 one hundred percent these five points.
