Sourced and supplied by Al Imran Enterprises, Lahore, Pakistan. The LAPAR LPZ11-851B is a NAMUR solenoid valve with a DC 24 V coil, built to pilot double-acting and single-acting pneumatic actuators on quarter-turn valves such as butterfly and ball valves. Its joint face follows the international NAMUR, VDI and VDE 3845 standard, so the valve bolts directly onto actuators machined to that interface, and the same family also covers in-line pipe joints per ISO 5599-1 for skid-mounted pipework. Working pressure spans 0.15 MPa to 0.85 MPa on filtered dry compressed air, matching typical plant instrument-air supplies without conditioning gymnastics. The inner-pilot design keeps the valve compact on top of the actuator, while the class F insulated coil draws just 2.5 W to 6.5 W on DC excitation and responds within about 40 milliseconds — quick enough for sequencing duties, not just open-close isolation. Supply voltage tolerance of ±10% accommodates sagging plant DC buses, and cycle rates up to five per second cover modulating damper and divertor service. Environmental protection is IP66 with an ambient window from -20 °C to +60 °C, so the valve survives monsoon-season outdoor actuator packages and hot mill interiors alike. Cable entry is a standard M20 × 1.5 gland thread, and the ADC12 aluminium body has a stainless steel SS316 option for corrosive duties. In Pakistani industry these valves are everywhere automation happens quietly: sugar mill bagasse and juice handling dampers, cement plant material divertors, water treatment isolation banks and oil and gas terminal skids. They also fail predictably at the worst moment — mid-crushing season or mid-batch — which is why maintenance planners keep spares on hand. Al Imran Enterprises supplies genuine LAPAR valves nationwide from Lahore, verifies markings and coil voltage against manufacturer data before dispatch, and consolidates valves with the actuators, limit switch boxes and positioners around them.
