Characteristic
- The 3D position indicator can clearly display the position of the valve.
- Die cast aluminum alloy shell, powder coating, compact design, beautiful appearance, reduces valve packaging volume, reliable quality.
- Double line interface with double 1/2 NPT pipe interface.
- Signal feedback device.
- The switch position can be clearly identified by the indicator.
- The multi contact internal circuit board has 8 internal contacts (6 for switches and 2 for spiral electrical conduit connections). The wiring board meets the standards of micro switches, with optional DPDT switches and valve position transmitters (4-20mA), mechanical micro switches, proximity switches, magnetic switches, etc. It can also be used for connecting solenoid valves.
- Quick position cam; The adjustable cam of the limit switch is installed through splines and springs; The position of the switch cam can be quickly adjusted without the need for tools.
- Replace wiring with PCB board to prevent short circuit.
- Environmental temperature: -20~85 ℃, waterproof and dustproof protection level: IP67, explosion-proof level: ExdII BT6, Eexd IICT6, in compliance with EN50014/50018 standards.
- Dual wiring ports, standard contacts, safe and convenient wiring.
- The bracket is easy to install. There are 4 types of brackets that comply with NAMUR standards and ISO5211 standards. Any rotating actuator can be easily installed.
- Anti loosening bolt, the bolt will not fall off when attached to the upper cover during disassembly and assembly.
- Easy to install, the stainless steel spindle connection part and installation bracket comply with VDI/VDE 3845 and NAMUR standards.
- Corrosion prevention.
- Internal and external coatings: coated with epoxy polyester coating, resistant to cooling.
- The bracket material can be selected as SS304.
- There are two types: standard type and explosion-proof type. The standard model is ITS100
(1) Before installation, check that the product model, tag number, and specifications match the requirements. Inspect the entire valve for missing or loose parts.
(2) Prior to installation, clean the pipeline. Ensure there is sufficient straight pipe section at the valve inlet and install a filter. When connecting the valve body to the pipeline flanges, ensure coaxiality.
(3) Thoroughly clean the pipeline before installing the valve.
(4) The installation site should ensure the safety of personnel and equipment, facilitating operation, disassembly, and maintenance.
(5) The valve should be installed vertically upright on horizontal pipelines. If necessary, it can be installed at an angle, but horizontal installation should be avoided. For occasions with heavy valve weight or vibration, use a support frame.
(6) The medium flow direction must align with the arrow on the valve body. The air supply should be dry and oil-free. The valve should be used in environments with temperatures ranging from -20℃ to 55℃.
(1) Cleaning the Valve: For general media, cleaning with water is sufficient. For media harmful to health, first understand their properties and then select an appropriate cleaning method.
(2) Disassembly: Remove rust from exposed rusted parts first. Before derusting, protect the machined surfaces of precision parts such as the valve seat, valve plug, valve stem, and push rod. Use special tools when disassembling the valve seat.
(3) Valve Seat: Minor rust or wear on the sealing surface can be repaired by machining. If damage is severe, replace the seat. However, both repaired and replaced hard sealing surfaces must be lapped.
(4) Valve Stem: If the surface is damaged, it must be replaced.
(5) Damage to Push Rod, Guide, and Sealing Surfaces: Reverse-acting actuators must be replaced; direct-acting actuators can be reused after proper repair.
(6) Compression Spring: If there are cracks or other defects affecting strength, replace it immediately.
(7) Wear Parts: Packing, gaskets, and O-rings must be replaced entirely during each maintenance. Check the valve plug and diaphragm for cracks, aging, or corrosion that may cause future failures. Decide whether to replace them based on inspection results, but the diaphragm service life should not exceed 2-3 years.
(8) When reassembling the valve, ensure alignment. Tighten bolts diagonally and lubricate sliding parts. After reassembly, debug the valve according to the factory test items and methods. During this period, accurately adjust the packing compression force and the valve plug closing position.
