This series of valves is divided into three driving modes: manual, pneumatic, and electric. It has the advantages of smooth operation, small size, reliable use, good sealing performance, and long service life, and can be widely used in high fidelity equipment. The valve is powered by manually rotating the handle, compressed air pushing the cylinder, and motor transmission torque. The connecting rod mechanism is pushed (pulled) by the transmission rod, and the driving body moves along the axial direction. The driving body is connected to the valve plate through a swing rod or steel ball to complete the opening and closing actions of the valve plate. The medium of the valve is air and non corrosive gases. Characteristic: 1.All seals are made of fluororubber and designed without lubricants; 2.The valve body is welded internally with stainless steel, resulting in a low leakage rate; 3.The valve body adopts a reinforced rib structure and a side actuator mechanism design, with small volume, light weight, and beautiful appearance; 4.Adopting a dual guide bearing roller mechanism, the movement is smooth; The valve plate has an integral structure with uniform support. Basic Specifications: Scope of application: 1 × 105Pa~1.2 × 105Pa Pressure difference on the plug-in board when opened: ≤ 3 × 10Pa in any direction Valve body and seat leakage rate: 1.3 × 10Pa Ls First maintenance cycle: 20000 times Valve body baking temperature: ≤ 200 ºC when opened; When closed: ≤ 150 ºC Compressed air (only suitable for pneumatic): DN 63~200 : 0.4~0.7MPa DN 250 : 0.5~0.7MPa Valve opening or closing time: Pneumatic drive: ≤ 6s Electric drive: ≤ 50s Installation location: Any power supply Pneumatic drive: AC 220V50Hz, 6W or DC 24V, 3W Electric drive: DN63~250 for AC 220V50Hz, 25W or AC 380V50Hz, 25W (except for the above specifications, special specifications can be customized) Valve position indication: Manual drive: equipped with an opening and closing position indicator switch (micro switch) Pneumatic drive: equipped with opening and closing position indicator switch (micro switch) Electric drive: equipped with opening and closing position indicator switch (micro switch)
