Product Name: Connecting Rod Butterfly Valve
Product Code:
Nominal diameter: DN600~DN3000mm
Nominal pressure: PN0.25-PN1.0MPa
Design features:
_Oil-free lubrication
_Long service life
_It has the characteristics of high temperature resistance, friction resistance, corrosion resistance, etc
_The forms of valve actuators include electric, hydraulic, pneumatic, manual, etc
_Select materials according to different working conditions: carbon steel, stainless steel, etc
_Compact design
_The pressure provided by the special connecting rod mechanism acts on the center of the valve, and the sealing surface is evenly stressed with good sealing performance
_The drive shaft is close to the centerline of the valve, and only a small torque is required to open and close the valve
_The main connecting rod and the auxiliary connecting rod are almost the same length, which avoids the linkage mechanism from getting stuck under high temperature conditions
_In the initial stage of opening the valve and the final stage of closing the valve, the valve plate moves parallel to the valve seat, achieving frictionless movement between the valve plate and the valve seat
Sealing form:
a. Metal hard seal; The sealing surfaces of the valve body and valve plate are both made of metal overlay hard alloy, and the leakage can reach level V.
b. Soft seal; The valve body is made of metal, and the sealing surface of the valve plate is a single-layer rubber strip, with a leakage rate of up to level VI.
Suitable operating conditions:
Frequent opening and closing under high temperature and low pressure, with short opening and closing time The sealing pressure level can reach PN1.0MPa, the opening pressure difference can reach PN0.5MPa, and the operating temperature can reach 600 ℃. It is widely used in medium pipelines such as hot air, gas, and flue gas
Frequent changes in working temperature
Can turn off clean and dusty air and gas media
