Major considerations in the selection of a regulator are listed here. Within the requirements of your specific application, use this catalog to find the regulator that matches your parameters. Our standard products are only a starting point. We can modify or create a control that will solve your toughest application problem. Detailed information is available through your local TESCOM representative.
手动旋钮①
大号手动旋钮提供简单、低扭矩的压力设置。 某些型号的扳手或螺丝刀调整选项。
HANDKNOB
Large handknob provides easy, low torque pressure setting. Wrench or screwdriver adjust options on some models.
排气②
当把手向“减小”方向转动时，排气功能可以释放出口压力。
捕获的排气配置包括额外的端口，用于将排出的流体从调节器的排气阀中排出。
非排气功能可用于不需要排气的液压或其他应用。
VENTING
Venting feature enables relieving of the outlet pressure when the handknob is turned in the “decrease” direction.
Captured venting configuration includes extra port to pipe away expelled fluids from a regulator’s vent valve.
Non-venting feature available for hydraulic or other applications where venting is not desirable.
流量 – Cv
CV 是调节器流量的量度。 流量系数是指 1 GPM 水在 1 psi 下降时通过主阀的流量。 气体服务的系数必须由入口与出口压力之比确定。
FLOW CAPACITY – Cv
Cv is a measure of regulator flow capacity. The flow coefficient refers to the flow of one GPM of water at one psi drop across the main valve. The coefficient for gaseous service must be determined from the ratio of inlet to outlet pressure.
主体材料③
黄铜、铝或不锈钢（300、316 型）等。
BODY MATERIALS
Brass, aluminum or stainless steel (Type 300, 316) and others.
可用的出口压力范围
从 50 mm Hg 绝对压力到 15 psig / 1 bar，范围高达 300-20,000 psig / 21-1379 bar。
OUTLET PRESSURE RANGES AVAILABLE
Starting at 50 mm Hg absolute to 15 psig / 1 bar, ranging up to 300-20,000 psig / 21-1379 bar.
加载 - 弹簧、圆顶、气动、电子④
加载是指用于平衡出口压力的方法。 弹簧加载与带手动调节的直接作用调节器一起使用。
圆顶加载*常用于高流量、快速响应型应用。
空气执行器提供高达 15,000 psig /1035 bar 的出口压力，信号仅为 100 psig / 6.9 bar。
TESCOM 电子控制器是另一种加载选项。
LOADING – Spring, Dome, Air Actuated, Electronic
Loading refers to the method used to balance the outlet pressure. Spring loading is used with direct acting regulators with handknob adjustment.
Dome loading is most often used in high flow, quick response type applications.
Air Actuator provides outlet pressures up to 15,000 psig /1035 bar with a signal of only 100 psig / 6.9 bar.
A TESCOM electronic controller is another loading option.
面板安装
某些型号标准设置。 其他的额外选择。
PANEL MOUNTING
Standard on some models. Extra option on others.
传感 – 隔膜或活塞⑤
隔膜为高达 500 psig / 35 bar 的出口压力范围提供灵敏和准确的调节。
活塞传感器为高达 20,000 psig / 1379 bar 的高出口压力提供高强度完整性。
SENSING – Diaphragm or Piston
Diaphragms provide sensitive and accurate regulation for outlet pressure ranges up to 500 psig / 35 bar.
Piston sensors provide high strength integrity for high outlet pressures up to 20,000 psig / 1379 bar.
入口压力范围
低于大气压至 20,000 psig / 1379 bar。
INLET PRESSURE RANGES
Sub-atmospheric to 20,000 psig / 1379 bar.
端口⑥

主阀 – 平衡和不平衡⑦
平衡设计用于减少入口压力衰减的影响，并且在某些型号中提供增加的流量。
不平衡阀简单和经济。
MAIN VALVES – Balanced and Unbalanced
Balanced design is used to reduce the effect of decaying inlet pressure and in certain models provides increased flow capacity.
Unbalanced valve offers simplicity and economy.
