|
The products are summed up:
The soft sealed centre line which our company develops, to inserting type butterfly's valve, a pair of partial flange type butterfly's valve structure is compact, it is relaxed that 90° turns the switch round, it is reliable to seal , have long performance life, used in water works , power plant , steel factory , papermaking , chemical industry , diet ,etc. supporting while draining off water systematically extensively, the conduct regulates and closes at using. |
Characteristic of the products:
1, valve this adopt pairs of partial structure , is it imprison urgent sealed function to have , reliable sealing property have.
2, seal packs of material select for use stainless steel and man nitrile able to bear oil rubber mate, have long performance life.
3, rubber is it is it can lie valve at the body , can lie butterfly at the board too to enclose to seal, the medium of applicable different characteristics, for users to choose.
4, butterfly's board adopts the frame structure, the intensity is high, is it flow area to be heavy to pass, is it hinder little to shed.
5, whole roast paint , can prevent the corrosion and only change the sealed material of sealed valve seat effectively , can use it in different medium .
6, valve this have two-way sealed function, when installing the control that the medium flowed into, free of the space position too , can install in any direction .
7, this valve of structure is unique , it is flexible to operate, save effort , it is convenient. |
