area.
认证
Certifications
材质：
Material:
所有压力承受部件都通过化学物理测试检验。铸造阀门符合MSS SP55标准，SP25标志标准和SP135设计结构标准。
All pressure-retaining parts have certified chemical
and physical test reports. Cast valves meet MSS SP55 standards, SP25 for
marking and SP135 for design.
测试：
Testing:
阀门按照美国国家标准化组织ANSI B16.34标准进行测试，金属阀座和弹性阀座气泡阀座符合CL IV四级泄漏标准。
Valves are tested per ANSI B16.34 and meet CL
IV leakage for metal seats and bubble-tight for resilient seats.
执行器
Actuators
 阀杆：
Stems:
美国国家标准化组织ANSI Class 150压力等级和550 CWP压力等级
ANSI Class 150 and 550 CWP
手动执行器轴是单导短梯形螺纹，带一件重型焊接夹子。这种夹子设置用来将关闭推力不通过螺栓负载直接转移到闸板上。
Manual actuator stems are single lead stub acme
threads with one piece heavy duty clip welded on. The clip is set to transfer
closing thrust loads directly to gate and not through bolts.
美国国家标准化组织ANSI Class 300压力等级
ANSI Class 300
手动执行器轴是单导短梯形螺纹。执行器阀盖阀杆连接是螺纹开口块联轴节，并采用螺栓连接在一起。
Manual actuator stems are single load stub acme
threads. The actuator bonnet stem connection is a threaded split block
coupling that is bolted together.
手轮：

Handwheels are sized for 80 lb. rim pull.
链轮：
Chainwheels:
链轮设计边缘拉力最大为100磅。
Chainwheels are sized for 100 lb. maximum rim
pull.
液动缸体：
Hydraulic Cylinder:
液动缸体设计用于操作1500 psi (10,345 kPa)及3000 psi (20,685 kPa)非冲击性压力。
Hydraulic cylinders are sized for operation at
1500 psi (10,345 kPa) and are capable of 3000 psi (20,685 kPa) non-shock
pressure.

阀盖
Bonnets
如果阀门应用在压力500 psi (3795 kPa)以上的应用环境中，则需要配置整体阀盖，带由一个压力自紧密封和一个重型编制平板环组成的杆密封。
For valves with service above 550 psi (3795 kPa),
an integral bonnet with a rod seal consisting of a pressure energized
seal and a heavy duty braided scraper ring is required. Seal and scraper
are replaceable without removing the bonnet or rod.
