Butterfly Valve for drainage
Our products have many series, we can do any kinds according to customer's requirement, can do different standards, such as ISO, GB, DIN, API, BS, JIS. Customers can buy or wholesale different items at one time by combine goods together.
We can design the products accprding to your special request. OEM is welcome too.
Advantages of Butterfly Valves:
(1)Smaller, Lighter and Economical
(2)On-off flow control capability at quarter turn
(3)Unaffected by precipitates
(4)Scrach Proof: No metal to metal friction
(5)Easy installation for all actuators: Hand Lever, pneumatic, hydraulic and electrical
(6)Low Pressure Loss
(7)Full Tightness prevents jamming
(8)Easy Replacetable seat
(9)Novel and reasonable design, special structure, light
(10)Easy instllation and mintenance. It can be mounted wherever needed.
(11)Tiny operative moment, quick 90 degrees on-off operation.
(12)Miniminzed operating torque, energy saving.
(13)Flow curve tending to straight line. Excellent regulation performance.
(14)Long servie life. Standing the test of tens of thousands opening/closing operation.
(15)Bubbles-tight sealing with no leakage under the pressure test.
(16)Wide selection of materials, applicable for various medeium
