Introduction ?????? Korea I-TORK (ITS-100) valve limit switch box is automatic valve control system detects a state of the field instrument to the valve open or closed position to switch the signal output was programmed sampling receiver or computer search, the next step after confirmation procedure. The product can also be used as an important valve automation systems and remote alarm indication chain protection purposes. Novel and beautiful design, with three-dimensional position indicator can be clearly identified and show the valve location, in the internal 8 PCB circuit board wiring connected contact convenient to prevent short circuits, control of environmental requirements according to site selection proximity switches, magnetic switches and installation signal feedback device. ? Valve limit switch box is automatic control system to detect the state of a field instrument valves for the valve open or closed position to switch the output signal is received by the control box or computer search sampling program to the next step after confirmation . The product can also be used as an important valve automation systems and remote alarm indication chain protection purposes. Specifications ?????? 1, the three-dimensional position indicator can clearly show the valve location. 2, die-casting aluminum casing, powder coating, compact design looks, reducing packaging volume valve, reliable quality. 3, two-wire interface? Dual 1/2? NPT pipe interface. 4, the signal feedback device. 5, switch position indicator clearly identified. 6, the internal contacts within the multi-access board 8 contacts (6 for switches, 2 for spiral electrical conduit link) patch panels comply with the standard micro-switch, there DPDT switch selectable and valve position transmitter (4 ~ 20mA), a mechanical micro switches, proximity and can be connected to the solenoid valve switches, magnetic switches. 7, "Quick Position" cam; adjustable limit switch cam splined and spring installation; switch cam position can be quickly adjusted without tools. 8, with the? PCB? Replace wiring board to prevent short circuits. 9, the ambient temperature: -20 ~ 85 ℃, waterproof and dustproof protection class: IP67, explosion-proof grade: ExdII BT6, Eexd IICT6, in line with EN50014 / 50018 standard??. 10, dual connection port, standard contact, wiring safe and convenient. 11, there are four kinds of brackets for easy installation in accordance with NAMUR bracket, stand in line with ISO5211 standards, any rotation of the actuator Jieke easily installed. 12, anti-off bolts, bolts attached to the removable cover when not fall off. 13, easy to install, stainless steel shaft and mounting brackets are in line with VDI / VDE? 3845,? NAMUR? Standards. 14, anti-corrosion. 15, internal and external coating: Epoxy coating - polyester coating, anti coorsion. 16, the stent material can be selected: SS304 ?. 17, there are two kinds of standard and explosion-proof.
