Peumatic triple eccentric butterfly valves
features
Our latest high-powered triple eccentric butterfly valve, valve body adopts triple eccentric structure, the disc and sealing institutions with unique design, excellent cutting performance and durability, and also has double function of cutting and adjusting. It has small volume, light weight, easy maintenance, economical and practical, widely used in metallurgical, chemical, petroleum, thermodynamic, energy, light industry, etc. It has the following advantages:
1, small volume, light weight, good cutting performance.
2 the disc sealing surface is designed as conical surface relative to disc axis center, making the disc sealing surface and seat sealing have contact angle, which is evenly around the circumference of a thin wedge is mutually, the disc circle vertical sealing line is oval curve, both functioned as sealing compensation.
3, disc sealing in the closed position, force uniformly, high bearing pressure ability, The disc in the opening process, sealing surface each point leave completely from the seat sealing movement, no squeeze phenomenon, no friction, open torque is minimal. Therefore, the cost is low, sealing performance is good, service life is long.
4 all kinds of sealing structure for choice, ensure service life and reliability. Butterfly valve sealing ring has integral soft sealing ring (PTFE, C - TFE, G - TFE), hardening metal piece, integral and hard alloy, applicable to all kinds of conditions.
5 can realize two-way sealing function, which has adjust and cut function.
6 actuators with low friction, high efficiency, large thrust, good safety.
7, the design of smart and combined actuators (manual device), can guarantee the direction of optional installation and flexible control.
8 simple, reliable integrated stroke indicatore and limit switches and solenoid valve combined installation, without external connecting pipes and reducing the leakage.
9 various actuators for selection, and meet different user requirements.
10, convenient maintenance and assembly with superior performance and price.
