High-temperature nitric acid special type regulator to rely on themselves within the medium flows through the valve's own pressure, temperature, as energy drive valve work automatically, do not need the power converter and secondary instrument. Also called self-reliance type control valve.

special regulator without additional energy self-reliance type, high-temperature nitric acid can work without electric airless place, convenient and save the energy. Pressure piecewise range and cross each other, high precision of adjustment. Pressure setting can be set in a continuous during operation. After the valve pressure regulation, valve pressure before and after the valve pressure ratio of 10:1 ~ 10:8. Rubber diaphragm detection, high measurement precision, actuator. Using pressure balance mechanism, the regulator is responsive, precise control.

special high-temperature nitric acid self-reliance type regulator

special high-temperature nitric acid self-reliance type regulator is the main technical parameters of the nominal diameter:

note: does the effective area of the corresponding pressure setting limits do not apply to 6 - 250.

special high-temperature nitric acid self-reliance type valve installation key

1, the valve used in gas or low viscosity liquid medium, usually type ZZY self-reliance type pressure regulator for vertical installed in a horizontal pipe, when position space does not allow to flip or inclined outfit.

2, for ease of maintenance and operation, the pressure regulating valve should leave proper space all around.

3, when the medium is clean gas or liquid, the valve before the filter is not installed.

4, the pressure regulating valve size is too large, DN 100 or higher) , shall have the fixed bracket when confirmed that medium is very clean, 3 is not installed.

5, the location is not allowed, by-pass valve ( Manual) Can be omitted, We do not recommend) 。

6, the valve group after user can be selected according to need check Industrial Valves, relief Industrial Valves, etc.

7, valve used in steam or high viscosity liquid medium, usually type ZZY self-reliance type pressure regulator for inverted installed in a horizontal pipe, condenser, Steam with self-reliance type) Should be higher than the pressure regulating valve actuator and below the valve before and after taking over. Before using the condenser shall be filled with cold water, irrigation time after about 3 months.
