HKD 多級降壓高壓差調節閥用于精確控制高溫、高壓、高壓差以及含有固體顆粒流體的流量和壓力。該閥綜合了普通式、多孔式和迷宮式低噪音調節閥的優點，能防止液體空化產生汽蝕，減小了高速流體對閥內件的沖刷，降低噪音。
調節閥的泄漏量符合ANSI B16.104標準。調節閥配用多彈簧薄膜或氣缸執行機構，其結構緊湊，輸出力大。
本產品符合GB/T4213-2008標準。
Mluti-stage Pressure Reducing High Pressure Drop Control Valves
HKD Mluti-stage Pressure Reducing High Pressure Drop Control Valves are used to control high temperature, high pressure and high pressure drops. It can be used to control flow and pressure of fluid with solid particles. It combines advantages of common type, porous type and Labyrinth type, so that it can prevent cavatition , reduce high speed fluid scouring trim and noise.
The leakage complies with the ANSI B16.104 standards. The actuator integrated with simplest mechanisms utilizes a compact yet powerful diaphragm actuator loaded with multiple springs or a cylinder.
This product complies with the GB/T4213-2008 standards.
