Long framework with rolling friction two-way pressure hard seal butterfly valve CMDS944/364/344 h/F/W

product description:

long framework with rolling friction two-way pressure hard seal butterfly valve is a new generation of products, activities seat and long legs and plane bearing structure, the new activity under reverse pressure can automatically adjust the compression seating sha-lu interface valve position in the activity, make whole sealing are not compression, and realize the reverse full differential pressure seal. Butterfly valve special geometric structure design, make the valve plate has the function of the closed tight when open the valve, as long as the valve shaft rotate it slightly, all from the valve seat, valve plate that is to reduce the friction, make the open torque presents the minimum best, sealed sealed a reliable, durable, widely used in urban heating, water conservancy projects, water, electric power circulating water, oil, chemical industry, etc.

long framework with rolling friction two-way pressure hard seal butterfly valve product features:

this product can be used for the heating system it mainly features below

1, the product is butterfly Industrial Valves suitable for thermal can replace the traditional ball valve on the return water pipe in the pipe. This butterfly valve compact structure, small volume, light weight, flexible operation features instead of ball valve to reduce the cost, is of great economic benefit, realize the two-way pipeline Industrial Valves pressure adjusting flow and the function of the cutting fluid.

2, the activities of the special structure can be adjusted seating sha-lu and seat position, adjust the sealing pressure, make the sealing surface is not easy to damage, improve the service life of the valve.

3 multi-level hard seal butterfly Industrial Valves, this product is a two-way pressure than normal one-way seal butterfly valve, realize the two-way sealing function, can achieve full reverse pressure differential pressure, valve domestic enterprises fail to achieve full reverse pressure differential pressure requirements.

4, this product is a two-way pressure multi-level hard seal butterfly valve has the function of two-way sealing, small flow resistance, good hydraulic characteristics, flow characteristic of approximate straight line, energy-saving effect is good. When installation is not restricted by medium flow direction, also not affected by spatial location, can be installed in any direction.

5, the butterfly valve sealing performance and reliable, opening and closing, the number more than 5000 times more than 5 years service life

6, the valve plate adopts the structure accords with the balance of the fluid mechanics performance flow design, drag coefficient 0 or less when valve is fully open. 15.

7, this product is a two-way the maximum temperature reached 300 ℃, pressure butterfly valve can be applied to heat pipe steam or overheating can medium, reverse in backwater pipeline double pressure can guarantee no leakage requirement, will not affect valve sealing performance by the change in temperature.
