Your Leading Butterfly Valve Supplier
New Lotoke Industry Group Co., Ltd, with a registered capital of RMB 113 million, has a factory area of more than 25,000 square meters and a building area of about 20,000 square meters. The group has more than 200 sets of high-precision machining centers and CNC machine tools, physical and chemical tests, mechanical performance tests, low leakage test (FE Test), ultra-high temperature test, ultra-low temperature test, product life test, sealing test, spectral testing, non-destructive testing and other types of complete processing and testing equipment.
The leading products of New Lotoke are five eccentric ball butterfly valves: all-metal sealing, double sealing, bidirectional sealing; one million times pressure switching, large caliber, general & special materials; ultra-high temperature (1200°C), ultra-low temperature (-196°C), ultra-high pressure (2500LB) and other high-end ball butterfly valves.
Specialized ball butterfly valves fully combine the advantages of frictionless, low torque, high sealing performance of ball valves and the advantages of butterfly valves, such as small size, light weight, easy to install and so on.
A new generation of ball butterfly valves completely realize frictionless spherical sealing, low torque, bi-directional pressure 1:1 zero leakage, pipe and valve with the same life (design life of 30 years), has been applied in large quantities to urban heating pipe networks at all levels and power generation steam systems.

Introduction to butterfly valve technology
Two generations of father's technical heritage, specializing in butterfly valves and ball valves R & D and manufacturing.
The world's first ball butterfly valve: five eccentric, frictionless, sealing self-cleaning.
Combining the self-cleaning and stable sealing performance of ball valves and the light weight and easy installation of butterfly valves.

New generation butterfly valve structure characteristics
Advanced all-metal washout resistance
Comparison of multi-layer and all-metal media washout
Sealed self-cleaning rings
Seat metal hard seal ring front self-cleaning ring, not only has an independent sealing effect, the valve can be closed in advance to clean the particles attached to the valve plate.
Overlay Stellite Carbide
The valve plate sealing part is overlay welded with Stellite carbide, with a thickness of 3 millimeters, solving the problem that the sealing part of the ordinary valve plate is not resistant to medium scouring.
Drive Spline Connection
Drive spline connection, straight plug and play, no need to install or remove special tools.
Dynamically balanced packing systems
Automatically adjusts the packing box space and pressure loss caused by packing wear to keep the packing box at constant pressure without manual adjustment.
Steel self-locking
Tie rod actuation with steel self-locking for more stable valve sealing during reverse pressure.
Upper and lower double stem design
Upper and lower double stem design, provide more space for flow, compared with the overall stem design, the same specification media flow efficiency increased by about 10%.
