Quality is everything! US Walker (WORK) import manual control valve actuator is automatic industrial process control systems for air, steam, gas, water, distilled water, chilled brine electroplating waste and other liquid media, but also for the oil viscosity of less than 4E class. Widely used in petroleum, chemical, textile, food, pharmaceutical, building materials and other production and scientific research departments and bathrooms, dining room, air conditioning and other facilities in people's daily lives. Also be used to open and close the vacuum line from the role. How it works: normally open: automatic control valve need to manually handle must be open; when the coil is energized, the handle can be rotated manually controlled valve switch. Normally closed: automatic control valve need to manually handle must be turned off; when the coil is energized, the handle can be rotated manually controlled valve switch. General parameters: For media: air, water, oil Connection: threaded, flanged control: NC Body material: stainless steel, cast iron Pressure: 0.01 ~ 20MPa Medium temperature: -10 ~ + 80 ℃ medium viscosity: less than 50CSt (greater than to be customized) protection performance: IP65 Power supply voltage: DC3 ~ 127V AC36 ~ 380V Leakage: Zero Fire control with manual pressure solenoid valve stainless steel Specifications: Make the user when ordering provide the following information:? a nominal diameter ( mm), PN (MPa), and the operating temperature range of 2? straight before the pressure regulating valve, the valve pressure 3? media name and status at 4? single-seat control valve supply voltage (220V or 380V, the default 220V) 5? Input signal: 4-20mA, or 1-5V (default 4-20mA) 6 single-seat control valve body, the trim material requirements of seven other special requirements (such as corrosion resistance requirements, proof grade requirements, leakage class limits?? , etc.) United States Walker (WORK) Valve Chinese agents welcome you to inquire and order!
