Engineered for heavy duty, maintenance free performance, the Cameron Fully Welded Ball Valve is commonly selected for a number of applications, including:One of the most trusted valves in the petroleum industry, it

combines the strength of forged components with a lightweight and compact spherical design.

Cameron Fully Welded Ball Valves satisfy ASME/ANSI 150 through 2500 (PN 20 through PN 420) and API 2000 through

10,000 standards. Made of forged steel to assure uniform fine grain structure and toughness, they may be specified in sizes from 2 in. to 56 in. (50 mm to 1400 mm).

STEM SEALS Delta seals and lip seals made of PTFE are incorporated in the upper stem area. PTFE is a low friction,non-deteriorating material that is not subject to rapid decompression explosion. Most valve sizes have a provision for the injection of sealant to establish a secondary seal.

TRUNNION SUPPORTED BALL ALLOWS LOW TORQUE OPERATION

Regardless of size or pressure rating, every Cameron ball valve is trunnion mounted.High strength forged stems are

located in PTFE impregnated

stainless steels bearings for smooth, accurate operations.Trunnion mounted stems absorb the thrust from line pressure,

preventing excess friction between the ball and seats, so even at full rated working pressure, operating torque stays low.

DOUBLE BLOCK AND BLEED

Whether in the fully open or fully closed position, pressure on each side of the ball is blocked from the body cavity by the seat ring.The body cavity can then be bled down or drained through the

body port.When you block and bleed a

Cameron Ball Valve the following can be accomplished:

TEST VALVE INTEGRITY

When Cameron Ball Valve body is vented this verifies the seat seals integrity. This test can be performed with the valve open or closed prior to facility maintenance. By verifying valve integrity unforeseen valve leakage can be prevented.

SECONDARY SEAT SEAL

The sealant injection system provides a fast, simple way of restoring tight shut off if any foreign object should damage the sealing surfaces.

The injection system can also be used for routine flushing of the seat ring area in services where this may be required.

阀杆密封

PTFE 三角形密封和唇形密封共同组成阀杆上部区域密封。PTFE 是低摩擦不老化的材料， 不会产生快速失压爆破。对于2"及以上尺寸阀杆， 还将提供密封脂注入系统用以建立二级密封。枢轴固定球

保证低扭矩操作无论尺寸大小或压力等级高低， 每台卡麦隆球阀均采用枢轴式固定球。高强度的锻钢阀杆由外包PTFE 的不锈钢轴承支撑做平滑精确的转动。枢轴支撑的阀杆可以吸收管线压力产生的推力，防止阀球和阀座之间的摩擦增加。因此即使在全压差下， 操作扭矩依然保持很低。双关断与排放无论阀门处于全开或全关位置， 阀座环都能将阀腔与球体上下游管线压力隔离， 阀腔可放空或通过阀体排污口排污。

当卡麦隆球阀关断并排放时可以实现以下功能：测试阀门完整性卡麦隆球阀阀腔排空时可以证明阀座密封的完好性。对设备进行维护之前可在阀门开或关时进行该测试。通过确认阀门的完整性， 可以避免不可预见的阀门泄漏。

二级阀座密封如果异物损坏了密封面， 二级阀座密封脂注入系统可提供一种快速简单的恢复紧密关断的方法。如有必要， 注脂系统也可用于周期性清洗阀座环密封区域。
