此處列出了選擇調節閥的主要考慮因素。 根據您特定應用的要求，使用此目錄查找與您的參數匹配的調節器。 標準產品只是一個起點。 可以通過修改或創建一個控件來解決您最棘手的應用問題。 詳細信息可通過您當地的 TESCOM 代表獲得。
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.
手動旋鈕①
大號手動旋鈕提供簡單、低扭矩的壓力設置。 某些型號的扳手或螺絲刀調整選項。
HANDKNOB
Large handknob provides easy, low torque pressure setting. Wrench or screwdriver adjust options on some models.
排氣②
當把手向“減小”方向轉動時，排氣功能可以釋放出口壓力。
捕獲的排氣配置包括額外的端口，用于將排出的流體從調節器的排氣閥中排出。
非排氣功能可用于不需要排氣的液壓或其他應用。
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 是調節器流量的量度。 流量系數是指 1 GPM 水在 1 psi 下降時通過主閥的流量。 氣體服務的系數必須由入口與出口壓力之比確定。
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.
主體材料③
黃銅、鋁或不銹鋼（300、316 型）等。
BODY MATERIALS
Brass, aluminum or stainless steel (Type 300, 316) and others.
可用的出口壓力范圍
從 50 mm Hg 絕對壓力到 15 psig / 1 bar，范圍高達 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.
加載 - 彈簧、圓頂、氣動、電子④
加載是指用于平衡出口壓力的方法。 彈簧加載與帶手動調節的直接作用調節器一起使用。
圓頂加載最常用于高流量、快速響應型應用。
空氣執行器提供高達 15,000 psig /1035 bar 的出口壓力，信號僅為 100 psig / 6.9 bar。
TESCOM 電子控制器是另一種加載選項。
LOADING – Spring, Dome, Air Actuated, Electronic
Loading refers to the methods 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.
面板安裝
某些型號標準設置。 其他的額外選擇。
PANEL MOUNTING
Standard on some models. Extra option on others.
傳感 – 隔膜或活塞⑤
隔膜為高達 500 psig / 35 bar 的出口壓力范圍提供靈敏和準確的調節。
活塞傳感器為高達 20,000 psig / 1379 bar 的高出口壓力提供高強度完整性。
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.
入口壓力范圍
低于大氣壓至 20,000 psig / 1379 bar。
INLET PRESSURE RANGES
Sub-atmospheric to 20,000 psig / 1379 bar.
端口⑥
尺寸：1/8" 至 1"
類型：NPTF（所有型號）、SAE、Aminco、MS33649、Slimline、BSP、焊接接頭。
PORTS
Sizes: 1/8" to 1"

主閥 – 平衡和不平衡⑦
平衡設計用于減少入口壓力衰減的影響，并且在某些型號中提供增加的流量。
不平衡閥簡單和經濟。
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.
