通径：DN80 - DN150
Sizes: 3" – 6" (80 – 150mm)
系列2300直接操作水减压阀适用于室内水系统流量有间歇性变化和变化迅速的终端水应用场合。也可以安装这个系列来调节如冲洗阀和快速旋塞阀这类快速反应设备的水流。这个系列2300被推荐用于打算将城市水压降低以供应卫生洁具，避免出现猛烈的压力波动现象。
Series 2300 Direct Operated Water Pressure Reducing
Valves are designed for dead-end water service where the flow is intermittent
and changes rapidly, as on domestic water system. This Series is also
installed to regulate the flow of water to such fast acting equipment
as flushometers and snap cocks. The Series 2300 is recommended where city
water pressure is to be reduced to supply plumbing fixtures to prevent
violent pressure fluctuations.
特点
Features
- 一个基本平衡的单阀座最大限度减小进口压力变化对输出压力的影响。
An essentially balanced single seat minimizes
variation in delivery pressure resulting from varying inlet pressure
- 一个大型海卡橡胶隔膜确保对于压力减少最轻微变化的灵敏反应。
A large Hycar diaphragm ensures a sensitive response
to the slightest changes in reduced pressure
- 无填料结构，避免填料函的摩擦
Packless design eliminates stuffing box friction
- 海卡合成橡胶单阀座适用于终端关闭场合，防止当需要无流量时出现压力蠕变。
Hycar composition single seat provides for dead-end
shutoff and prevents pressure-creep when no flow is required
- 自对齐结构。不需要底部法兰内的阀杆引导，也不需要可能导致错误操作的直接采集点。
Self-aligning design. Eliminates the need for
a stem guide in the bottom flanges and remove a point of direct collection
that can cause faulty operation
- 阀瓣和柱塞经过定位，最大限度减小由于污垢而堵塞的可能性。
Disc and piston are located to minimize the possibility
of obstruction by dirt
- 大型压力板为隔膜提供足够的支撑 - 确保更长的使用寿命
Large pressure plate gives ample support to the
diaphragm – assuring long life
- 没有可能出现粘住的填料函
No stuffing boxes to stick
- 完备的结构，不需要控制线
Self contained design, requires no control lines
- 通过拆卸法兰盖或弹簧腔室，可以接近所有内部部件。常规的维护保养可以在保持阀门在线的情况下进行。
All internal parts accessible by removing blind
flange or spring chamber. Regular maintenance can be performed with
the valve body in line
- 不需要维护填料函
No stuffing box maintenance required
应用
Applications
- 工业厂房的洗手间和工艺生产线
Industrial plants for washrooms and processing
operations
- 公寓建筑，宾馆酒店，办公大楼和医院，每一层都配置以提供稳定的压力。
Apartment buildings, hotels, office buildings
and hospitals to provide each floor with a steady pressure.
- 市政或生活用水主管线，用于保持恒定的压力
Municipal or plant water main to maintain constant
pressure

Series 2300
- 这种阀门结构最大限度减小任何污垢的危险，延长阀杆引导的使用寿命
The design of this valve minimizes any danger
of dirt lodging in the stem guide.
- 基本平衡单阀座最大限度减小进口压力变化对输出压力的影响。
Essentially balanced single seat minimizes a variation
in delivery pressure resulting from a varying inlet pressure.
- 一个大型开卡橡胶隔膜确保对压力减少最轻微变化的灵敏反应。
A large Hycar diaphragm ensures a sensitive response
to the slightest change in reduced pressure.
- 这种结构是完整的，不需要控制线。
This design being selfcontained, no control lines
are required.
- 适用于关闭水流。不会出现振动或产生水锤。操作顺利宁静。
Designed to close against the flow. Will not chatter
or produce water hammer. Operates smoothly and quietly.
底部法兰内不需要阀杆引导，避免淤积污垢。这些阀门是自我对齐，阀瓣的引导不依赖于螺栓底部法兰。
No stem guide in bottom flange to collect dirt.
These valves are self-aligning and the guiding of the disc is independent
of the bolted bottom flange. |
