机能符号 Symbol 节流阀 Cartridge Needle Valve 技术参数 Specifications ·工 作压 力 Operating Pressure 350BAR ·流 量 Flow 28L/min ·温 度 Temperature -40°C to +120°(-40°F to+250°F) ·插 孔 Cavity T-13A ·流 体 Fluids Mineral-based fluids with viscosities of 7.4 to 420 cSt. Adjustment Sensitivity at 7 bar Differential 产品特性 Features ·由于针阀并不具备压力补偿的结构,固定的小孔将会使流量大小与1 口,2口压差的平方根成比例 Because needle Valve are non-compensating devices, the fixed orifice size will regulate flow through the valve in proportion to the square root of the pressure differential across ports 1 and 2. ·平衡的调节结构可以保证在高压力情况下,亦可轻松调节 A balanced adjustment mechanism allows for easy adjustment even at high pressures ·锐边小孔的设计可以最大化地减小粘度对于流量变化的影响 The sharp-edged orifice design minimizes flow variations due to viscosity changes
