China 35kV Safety Shutter Mechanism Device (Connecting Rod Type) Manufacturer, Supplier, Factory

SOLH XTO674 and INA14 inline check valves share the same structural platform with ultra-low 0.01MPa cracking pressure, compatible with both compressed air and clean water for anti-backflow protection in vacuum and low-pressure fluid pipelines. XTO674 is an all-brass cryogenic version working down to -30℃; INA14 standard series provides brass or SUS304 stainless steel body, equipped with standard NBR seals plus optional oil & high temp resistant FKM and weather-proof CR seals. Compact inline threaded design with flow arrow marking can be directly mounted in pipelines without extra brackets, effectively preventing vacuum loss and reverse airflow when installed between vacuum generators and suction cups. The two series feature identical overall dimensions and thread sizes for direct field interchange without pipe modification, widely applied in cryogenic equipment, vacuum production lines, corrosion-resistant high-temperature fluid circuits and general pneumatic & water pipelines for one-way pressure retention and backflow prevention.

SOLH MA economical stainless steel mini pneumatic cylinder covers bore sizes φ16/20/25/32/40/50/63 mm and is interchangeable with SMC CM2/CM3 series with outstanding cost performance. It adopts 304 stainless steel barrel and piston rod plus aluminum alloy end caps, offering rust resistance suitable for humid, mildly corrosive environments as well as clean production lines for food, electronics and packaging industries. Complete variants include MA standard double acting model, MTA single acting spring return, MSA single acting spring extend, MAD double rod synchronous cylinder and MAJ stroke adjustable type. MAC version with adjustable air cushion is optional for high-speed operation. All models are equipped with built-in magnetic ring, compatible with CS1-G and M9B magnetic switches for position feedback. Standard rubber cushion is supplied, and optional adjustable air cushion effectively reduces impact and noise. Roll-crimped end cap structure ensures stable performance and enables oil-free operation with service life over 5 million cycles. Multiple mounting accessories are available, including cylindrical tail, clevis tail, flange, foot bracket and double clevis to fit diverse equipment layouts. Ideal for light & medium-load automation projects with budget constraints. A minimum 50% thrust safety margin is recommended during selection.

SOLH HSV series 3/2-way hand slide pneumatic valves adopt an inline sleeve push-pull integrated structure, fully consistent with the dimensional specifications of mainstream AirTAC HSV series and interchangeable with equivalent domestic counterparts. Designed without return springs and equipped with mechanical self-locking positioning, this valve switches airflow by axial pushing and pulling: pushing the sleeve forward connects the P inlet port and A working port for normal air supply; pulling backward disconnects the air intake and automatically links port A with the built-in R exhaust port to rapidly vent residual pressure inside rear pipelines and actuators. It serves as a dedicated safety shut-off switch for pneumatic branch pipelines and essential pressure relief valve for equipment maintenance work. Three standard ports are configured: P for main compressed air inlet, A for output to downstream pneumatic components, and an embedded built-in R exhaust port hidden inside the valve body. A wealth of specifications covering G1/8 up to G1 thread sizes are supplied, paired with three thread layout options (SF single inner & single outer thread, SS double outer threads, FF double inner threads); PT taper thread, G parallel thread and NPT thread are selectable to fit global piping standards. Constructed with hard-anodized aluminum alloy valve bodies, stainless steel anti-rust spools and high-performance NBR nitrile rubber sealing rings, the valve supports lubrication-free operation under filtered compressed air within 0~1.0 MPa rated working pressure and withstands test pressure up to 1.5 MPa. The operating push-pull force is controlled at 18~25 N for smooth operation, and the mechanical locking structure maintains the set position firmly without drifting or air leakage caused by accidental touching. Different from 4HV rotary hand valves used for forward/backward switching of double-acting cylinders, the HSV series is engineered exclusively for pipeline on-off and pressure release. It can be directly installed in series within air pipelines without extra mounting bases to save installation space. Widely deployed for isolating air supply before equipment overhaul, main air circuit safety cut-off of automation tooling, vacuum pipeline switching and branch circuit independent air source control, it effectively eliminates hidden dangers brought by residual pressure during maintenance and guarantees on-site operational safety.
