Quality is everything! US Walker (WORK) Self-pressure regulating valve imports is a no external energy (signal) and only rely on the media itself is modulated pressure changes automatically adjust the pressure of energy-saving products, which combines measurement, execution, control and many other functions until one, self-contained independent instrument control system. For the pressure of non-corrosive gases, liquids and steam and other media, regulators, or relief, holding pressure automatic control has a very significant energy savings. Imported Self-pressure regulating valve is widely used in petroleum, chemical, power, light industry, printing and dyeing industry automation system equipment in a variety of deceleration pressure gas, liquid and steam media, regulators, pressure relief, the regulator automatically. According to different working conditions can choose different types of valve structure and the different implementing agencies, in order to achieve the best control effect. Technical parameters: Nominal diameter: DN20-DN300mm Nominal: PN1.6-6.4MPa Temperature: ≤80 ℃, ≤350 ℃ membrane cap: A3,1Cr18Ni9Ti packing: PTFE, flexible graphite diaphragm: reinforced nylon rubber oil-resistant rubber, fluoro rubber imports Self-pressure regulating valve Product Application: petrochemical, power, metallurgy, light industry, heating system, gas mining output, gas transportation, water, steam, gas and a variety of low-viscosity media and other industries Department of Automatic Control System. When ordering, please provide the following information:? A nominal diameter (mm), nominal pressure (MPa), operating temperature range of two straight and before the pressure regulating valve, the valve pressure of 3 media name and status at 4 single seat??? valve supply voltage (220V or 380V, default 220V) 5 Input signal:??? 4-20mA, or 1-5V (default 4-20mA) 6 single-seat control valve body, the trim material requirements seven other special requirements (eg corrosion requirements, proof grade requirements, leakage class limits, etc.) USA Walker (WORK) Valves Chinese agents welcome your inquire and order!
