Solenoid Valve Installation Notes1. Ensure the flow arrow on the valve body matches the medium direction. Do not install in areas exposed to direct water dripping or splashing. Mount the valve vertically with the coil facing upward.2. The valve must operate reliably within a power supply fluctuation range of -10% to +15% of rated voltage.3. After installation, ensure no reverse pressure differential exists. Cycle the valve electrically several times to reach operating temperature before full commissioning.4. Thoroughly flush pipelines before installation. The medium must be clean—install a filter upstream of the valve.5. Install a bypass line to maintain system operation during valve maintenance or failure.

气流经过对称斜孔分成多束进入扩散室A后膨胀，减速后与反射套碰撞，然后反射到B室，在消声器中心处，气流束互相撞击、干涉。当两个声波相位相反时，使声波的振幅相互减弱达到消耗声能的目的。*后声波通过消声器内壁的消声材料，残余声能由于消声材料的细孔相摩擦而变成热能，再次达到降低声强的效果。
Working Principle: A solenoid valve contains a sealed chamber with multiple ports connected to different fluid lines. A movable plunger sits between two electromagnetic coils. When one coil is energized, it attracts the plunger, opening or closing specific ports. The inlet is normally open, allowing fluid (oil, air, etc.) to flow into selected discharge lines. Fluid pressure then drives a piston in a cylinder, which moves a rod to actuate mechanical devices. Thus, controlling the solenoid current controls mechanical motion.ClassificationBy medium/application: hydraulic, pneumatic, steam, gas, oil, fire-protection, refrigeration, corrosion-resistant, high-temp, high-pressure, zero-differential, cryogenic, vacuum, etc.By internal structure: pilot-operated, direct-acting, compound, self-latching, pulse, bistable, bidirectional, etc.By body material: cast iron, brass, cast steel, full stainless steel (304/316), non-metallic (ABS, PTFE).By pressure rating: vacuum (-0.1~0 MPa), low (0~0.8 MP...
The 10SR/DA pneumatic actuator uses a dual-rack-and-pinion mechanism with an aluminum alloy body. SR = spring-return (single-acting); DA = double-acting. Bore: Φ45–Φ400 mm. Standard models offer ±4° adjustability at 0° and 90° positions. Max theoretical torque @ 0.8 MPa: DA = 15,800 N·m; SR (K6 spring) = 9,696 N·m @ 0°, 7,488 N·m @ 90°.Main Features:1) Dual-rack design increasingly adopted to boost torque or reduce size (vs. traditional single-rack).2) Materials: Body—aluminum with hard-anodized finish (stainless for corrosive media, electropolished). Pinion shaft—stainless steel. Racks—stainless or die-cast aluminum, with composite bearings and wear rings to reduce friction and extend life. Seals—NBR O-rings (standard), FKM for high-temp, low-temp NBR for cold. Integrated anti-leak, bearing-guided shaft design ensures longevity.3) Oil-free lubrication—low friction, high reliability.4) Magnetic switch compatible for automated control.5) Mounting complies with internati...
In pneumatic (or hydraulic) circuits:A 2/3-way solenoid valve has: 1 inlet (from air supply), 1 outlet (to actuator), and 1 exhaust port (typically fitted with a silencer; optional if noise is acceptable).A 2/5-way solenoid valve has: 1 inlet, 1 forward outlet + 1 reverse outlet (to drive double-acting cylinder), and 1 forward exhaust + 1 reverse exhaust (with silencers).For small automation equipment, 8–12 mm industrial air tubing is typical. We recommend using our company’s reliable brand of solenoid valves.In electrical terms:2/3-way valves are usually single-coil; 2/5-way valves are typically double-coil. Common coil voltages: DC24V, AC220V.2/3-way valves come in NC (closed when de-energized) and NO (open when de-energized) types.• NC 2/3-way: Energize → open; de-energize → close (“momentary”).• NO 2/3-way: Energize → close; de-energize → open (“momentary”).2/5-Way Double-Solenoid Operation:Energize “forward” coil → forward port opens and latches (remains open after ...
Cylinder barrel bore requires high machining precision. Surface roughness depends on piston seal type: • O-ring seals: Grade 3 accuracy, Ra ≤ 0.4 μm • Y-ring seals: Grade 4–5 accuracy, Ra ≤ 0.4 μmCylindricity and roundness errors must not exceed half the dimensional tolerance. Perpendicularity between end face and bore must be within 2/3 of tolerance.If barrel surface finish is inadequate, friction between seal and bore increases, causing:• Elevated starting pressure• Crawling (jerky motion)• Accelerated seal wear → internal leakage → failure to meet performance specs.Prevention: Improve machining accuracy of barrel and rod surfaces.
I. Reliability1. Choose between normally closed (NC) and normally open (NO). NC (open when powered) is standard. Use NO (closed when powered) only when the valve must remain open for long durations with very brief closures.2. Life cycle testing is typically a type test. Note: China lacks a dedicated professional standard for solenoid valves—select manufacturers carefully.3. For high-frequency, fast-response applications, choose direct-acting valves. For large ports, select “fast-response” series.II. Safety1. Standard solenoid valves are not waterproof. Specify waterproof models if needed (customizable).2. The valve’s rated pressure must exceed the system’s maximum operating pressure to ensure longevity and safety.3. For corrosive fluids, select full stainless steel construction.III. EconomyMany valves are interchangeable. Among options meeting reliability, safety, and suitability criteria, choose the most cost-effective solution.
Normally-closed (NC) multi-media solenoid valves use an NC pilot solenoid. Normally-open (NO) versions, used where rapid closing is critical, employ an NO pilot solenoid.NC Design – Working Principle & Features:When de-energized, the plunger closes the pilot drain port under spring force. Inlet pressure (P) flows through a small orifice into the diaphragm chamber, creating higher pressure above the diaphragm. Combined with spring force, this pushes the diaphragm down to seal the main valve seat.When energized, the pilot opens, venting the diaphragm chamber. Since the pilot vent orifice is larger than the inlet orifice, chamber pressure drops rapidly. When upward force from P exceeds downward force, the diaphragm lifts, opening the main valve.NO Design – Working Principle:When de-energized, the plunger opens the pilot port and closes the vent (R). The diaphragm chamber vents, allowing inlet pressure to lift the diaphragm and open the main valve.
