The D971X electric soft-seated butterfly valve features an integrated structure and can be operated with a 220VAC power supply. It can also be equipped with a control module to receive control signals (4-20mADC or 1-5VDC) for adjustment. The electric soft-seated butterfly valve is known for its strong functionality, compact size, affordability, reliable performance, simple accessories, high flow capacity, and reduced leakage (down to 0.01%) for normal temperature and clean media by using valve plates with soft seals (rubber or PTFE rings). For high-temperature and high-pressure conditions, a triple eccentric hard-seated valve body can be selected. The electric soft-seated butterfly valve is widely applicable in industrial process automatic control systems across industries such as food, environmental protection, light industry, petrochemicals, educational equipment, papermaking, and power.

(1) Robust Features: Intelligent, adjustable, and switch-type.
(2) Compact Size: Only about 35% of the volume of similar products.
(3) Easy to Use: Single-phase power supply, simple wiring; spherical protruding structure for easier observation; no need for oiling or checking, waterproof and rustproof, can be installed at any angle.
(4) The protective device features dual limit switches, overheat protection, and overload protection. Full travel time options are 15, 30, 45, and 60 seconds, and it also includes manual operation capability.
(5) Intelligent CNC: The built-in modules adopt a single-chip computer and intelligent control software to directly receive standard signals (4-20mA DC / 1-5VDC) from computers or industrial instruments, achieving intelligent control of valve opening and precise positioning.
You can also opt for the 3810 series or NA series electronic angle positioners. The PSQ series or DYR series can also be chosen. Valves with DN400 or greater pipe size typically use 380VAC electric actuators.
