NovaTech®全开钻阀结合了锻造合金钢上身的强度,具有精密铸造,以最大限度地减少流动限制和流体湍流。概述NovaTech®钻头将锻造合金钢上身的冲击强度与精密铸造的优点相结合,以最小化流动限制和流体湍流。阀门进入两个版本 - 具有可更换的聚氨酯插入件或专利的Novatech®Cast-N-Place™插件。钻孔阀和座椅设计适用于所有主要制造商泥浆泵型号,用于无限多功能性和延长阀门和座椅寿命。它还减少了插入膨胀和运动,流体端开裂和冲洗。重型座椅增加金属到金属轴承区域,提供均匀的流体端载荷,同时减少流体终端应力和冲洗。NovaTech®Cast-N-Place™插入件通过经济高效的成型过程来提供传统的更换阀的显着优势,使插入件锁定到位。该过程增加了耐磨性和挤压性,提供较长的阀门寿命。Manufactured 100% in the U.S.A. of SAE 8620 alloy steel, these valves are designed to operate in pressures up to 7,500 psi and temperatures up to 71°C (160°F) for the standard urethane version and up to 149°C (300°F) for the Cast-N-Place™ version. Full open drilling seats are available in standard 2-inch and modified 1-inch tapers and offered in API-4 thru API-8 sizes for upstream oil and gas drilling applications.
