Technical Data: Joint size: DN10-DN65 Thread: BSP,BSPT,NPT,NPTF Welded: ISO1127/4200, DIN11850.1, DIN11850.2, DIN11850.3, SMS3008, ASME BPE Socket Welding Actuator:CF8 Valve body: CF8M, CF8 Seat seals: PTFE/NBR/EPDM Stem seals: PTFE/FKM Piston seals: FKM/NBR Applicable medium: Water, liquid, neutral gas, water steam, slight corrosive gas and liquid Temperature range: PTFE:-10 to +180 Ambient temperature: -10 to +60 degree Viscosity: Max 600mm2/s Installation: Any position Controlling medium: Air or neutral gas Controlling pressure range:0.3-1Mpa. Advantagement: 1.Easy installation, 2.large flux, low resistance(Y-type shape enlarged the flowing section, which could raise the flus by 30% and make it flows more smoothly.). 3.low energy consumption. 4.long life span(The valve stem material is AISSS316, its anti-corrosive ability is super strong. The PTFE sealing parts are in wedge shape , which help the stem adjust and lubriacate automaticlally.).
