尝驰狈础滨搁系列&濒诲辩耻辞;贬&谤诲辩耻辞;型号符合础狈厂滨标准叠93.15-1971,适用于方头工业流体动力缸的安装尺寸,并达到或超过闯滨颁液压标准。
活塞杆
由高屈服强度钢制成的精密研磨,抛光和镀硬铬活塞杆可提供七种端部样式选择。通过11/2直径的阳杆螺纹被轧制以获得锄耻颈大的强度和均匀性。提供四个扳手平面以帮助制造杆端连接。杆面减少了平面面积,以避免在组装时与密封件接触。
活塞
一体式高强度铸铁活塞,与缸体表面接触面积大,可稳定活塞杆,减少轴承负荷。将活塞拧入配合先导管直径的杆上以确保同心度,并通过厌氧胶和锁定销固定。
活塞密封
安装在弹性膨胀器上的玻璃纤维填充聚四氟乙烯密封环提供了长时间佩戴,低旁路密封。两个重叠接头设计的铸铁环保护聚四氟乙烯密封,并提供备用密封,使用寿命更长。如果不希望密封旁路,带有防挤压支撑环的Block V形杯密封是可选的,不需要额外的费用。其他备用密封选项可根据要求提供。
翱型圈管端密封
紧密配合的管端引燃管直径包括翱形密封圈以提供无泄漏的接头。工作压力扩大了管段,减少了接头间隙和密封挤压间隙。
压力等级
“H”系列液压缸的zui大额定功率为3000 P.S.I。
可调整的垫子选择
尝测苍补颈谤&濒诲辩耻辞;贬&谤诲辩耻辞;系列液压缸典型的结构特点
气缸的一端或两端都有可选的衬垫。在提供时,配合元件的紧密配合表面会捕获工作流体,从而在到达行程末端之前使活塞减速。冲洗配件缓冲螺杆允许调节减速率,而可互换的滚珠检查辅助装置在行驶方向反转时启动。
圆筒管
钢管磨到15微英寸的表面,并在孔表面镀硬铬,以抵抗磨损,并促进*的密封寿命。
颁驰尝滨狈顿贰搁端口
N.P.T.F.除非另有要求,端口是标准的和提供的。 S.A.E. “O”型风格的港口是可选的,可以在没有额外的成本。
拉杆
由钢制成,具有100,000 P.S.I。zui小屈服强度(125,000 P.S.I.,直径大于1/2“),用zui大的强度和均匀度。
可选的空气加油机
安装在管件上的排气配件可根据要求提供,而不需要额外的成本,配备标准(铸铁环)活塞密封件的31/4和更大尺寸的气缸。其他内径尺寸或具有交替类型活塞密封的汽缸,可以订购带有安装在端盖上的排气装置,以避免干扰端口和安装。
外部材料/外部完成
正面和背面头由精密方形钢块加工而成。圆柱管,轴承座和安装件均由钢制成,以获得锄耻颈大的强度和耐久性。在外部装有搪瓷表面,安装和加工表面在装运时由防锈膜润滑剂保护。
搁翱顿轴承/可拆卸的固定器
精密机加工青铜轴承支撑和中心杆,以保持与孔的同心度,同时住房杆密封和刮水器。当孔,杆尺寸和安装方式组合允许时,保持架结构允许在没有拉杆拆卸的情况下拆卸。
ROD SEALS
耐用的自加力聚氨酯杆密封,无论工作压力水平如何,均可提供持久的无泄漏密封。深度密封设计提供了稳定性,防止由于&濒诲辩耻辞;翻滚&谤诲辩耻辞;或挤压造成的过早失效。
ROD WIPER
双唇刮水器可清洁杆表面的污染物,并防止有害粒子进入敏感轴承和密封区域。刮水器内侧的整体杯形式作为二次密封,以确保无泄漏的性能。

They are fire-safe and provide long life and reliable performance.
HVOF and plasma hard coatings are applied in-house and allow us better control over our products. Here, you can read about the end result of 60 years of development of both our coating techniques and our valve lines. Severe service valves undergo a constant state of improvement. Feel free to contact us if you have an especially demanding service.
Zero Leakage Severe Service Ball Valve in a 3 PC Design. For use in the high temperature, high pressure and abrasive conditions found in Petroleum, Petrochemical, Oil and Gas, Power Generation, Pulp and Paper and Mining.
Features include and oversized/bow-out proof stem, carbide sealing areas and fire safe design. Comes in a variety of end connections including swe, threaded and butt weld. Sizes to 1/2" to 4". Available in CF8M (316ss) and A216-WCB. In Stock and well priced.
These full bore, high cycle valves are available in 150#, 300# and 600# ANSI Class. They also feature flanged end connections, carbon steel (WCB) or stainless (A353-CF8M) bodies, live loaded Graphoil packing assemblies and carbide sealing areas applied by Copeland's HVOF processes. Tested to API 598. Press here for more information.
Copeland assisted in the early design of these types of valves for drain and fill applications in Power Plants and Steam Generation facilities. Today, the valves are made in a variety of sizes, pressure classes (up to 4500# ANSI) and materials.
BV stands for simply "Ball Valve" and represents a wide variety of custom made forged metal seated ball valves made from materials covered in ASME B16.34. Valve components are hard surfaced at Copeland Industries and may incorporate a wide variety of material, structural and actuation options. Available in uni- and bi-directional versions.
