结构特点 DESIGN FEATURES
1. 结构紧凑,非常坚固,适用于高压高温应用领域。
A compact but extremely sturdy design for high pressure-temperature service.
2. 实心钨铬钴合金6楔板(备选项),确保较低的磨损和较长的使用寿命。
Solid Slite 6 wedge (optional) ensures low friction and long service life.
3. 1500磅级的阀门和用于蒸汽应用领域的阀门,其阀座是通过密封焊接到阀体上的。
For Class 1500 valves and for steam service, seats are seal-welded to the body.
4. 填料环经过4000 psi高压预压缩,具有完整的密封性能。
Packing rings are precompressed to 4000 psi to provide a high integrity seal.
5. 焊接阀帽阀门,阀帽经过螺纹旋进,旋进扭矩达到工程扭矩值,阀体阀帽连接是强度-焊接连接,这样具有双重保护防止泄露。(阀体/阀帽螺纹和强度-焊接连接)。
For welded bonnet valves, the bonnet is threaded in and torqued to an engineered torque value and the body bonnet joint is strength-welded, offering double protection against leakage. (Body/bonnet threads and strength-weld).
6. 全导向楔板减少阀座表面的磨损。
Fully guided wedge reduces wear on seating surfaces.
7. 可维修的2件式阀杆驱动。
Repairable 2-piece stem drive.
