The HLS small caliber single seat regulating valve is one of the CV3000 series products. The HLS small caliber single seat regulating valve has a compact structure and an S-shaped channel, which makes it characterized by high pressure drop loss, large flow rate, wide adjustable range, and high accuracy of flow characteristics

valve body
Type: Straight through single seat cast ball valve nominal diameter: 20mm, 25mm nominal pressure: ANSI 125, 150, 300, 600 JIS 10, 16, 20, 30, 40K PN1.6, 4.0, 6.4MPa Connection type: flange connection: FF, RF, RJ, LG, groove type, embedded flange standards: JIS B2201-1984, ANSI B16.5-1981, GB/T9112-9124-2000 Welding connection: socket welding SW Material: cast steel (ZG230-450), cast stainless steel (ZG1Cr18Ni9Ti, ZG0Cr18Ni12Mo2Ti), titanium, etc. Valve cover: room temperature type P): -17~+230 ℃ Elongation Type I (E1): -45~-17 ℃+230~+566 ℃ Elongation Type II (E2I): -100~-45 ℃ Elongation Type II (E2W): -196~-100 ℃ Note: The working temperature should not exceed the allowable range of various materials. Type of gland: bolt compression type Packing: V-shaped PTFE packing, PTFE impregnated asbestos packing, asbestos braided packing. Valve core type of internal components: single seat plunger type valve core. Flow characteristics: The metal valve seat has equal percentage characteristics (%) and linear characteristics (L), and the high-precision flow characteristics with Cv values ranging from 0.04 to 14 are in line with the IEC534-2 standard. The soft valve seat has equal percentage characteristics (%) and linear characteristics (L), and the reference flow characteristic curve. Note: Regarding the working temperature and pressure difference of the PTFE valve seat, the reference flow characteristic curve is made of stainless steel (1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti, 17-4PH, 9Cr18, 316L), stainless steel overlay with Stellite alloy, titanium, and corrosion-resistant alloys

actuator

Type: LHA multi spring thin film actuator Material: Ethylene propylene rubber with nylon cloth, Nitrile rubber with nylon cloth Spring range: 20-100, 80-240kPa Supply pressure: 140-400kPa Air source interface: Rc1/4 "Environmental temperature: -30~+70 ℃ Valve action type: Use positive or negative action actuator to achieve valve air closing or air opening Accessories: Positioner, air filter pressure reducer, holding valve, travel switch, valve position transmitter, solenoid valve, handwheel mechanism, etc

performance

Leakage metal valve seat: less than 0.01% of the rated capacity of the valve, in accordance with ANSI B16.104-1976 Class IV soft valve seat: less than 10-7 of the rated capacity of the valve, in accordance with ANSI B16.104-1976 Class IV backlash: with locator: less than 1% of the full stroke, without locator: less than 3% of the full stroke (LHA1 type less than 5% of the full stroke) Basic error: with locator: less than ± 1% of the full stroke, without locator: less than ± 5% of the full stroke. Note: Standard V-shaped polytetrafluoroethylene packing can be adjusted within a range of 50:1 (0.25 ≤ Cv ≤ 14) or 30:1 (CV ≤ 0.16)
