Imported pneumatic lug-type butterfly valve (Robot brand from Germany)
Product Introduction
The German-imported pneumatic lug-type butterfly valve from Robert is composed of two parts: a lug-type butterfly valve and a cylinder. Its main structural feature is that the valve body has lugs around the periphery and is designed as a single flange structure with screw holes. Due to the triple eccentric structure, the sealing performance is reliable, ensuring that the butterfly plate does not contact the sealing seat when opening, eliminating the uneven load on the sealing seat, extending the service life, ensuring reliable sealing performance, and having the characteristics of temperature resistance, wear resistance, and Corrosion and other advantages.

Product Features
, simple and compact structure, small operating torque, and fast rotation and opening.
, small and light, easy to disassemble and repair, and can be installed in any position.
The flow characteristics tend to be linear and the adjustment performance is good.
. The connection between the butterfly plate and the valve stem adopts a pinless structure, which overcomes possible internal leakage points.
The valve can be designed with flange connection and clamp connection.
The seals are replaceable and the sealing is reliable and achieves two-way sealing.
The butterfly plate can be spray-coated according to user requirements, such as nylon or polytetrafluoroethylene.
The outer circle of the butterfly plate adopts a spherical shape, which improves the sealing performance and extends the service life of the valve. It can open and close under pressure for more than 10,000 times and still maintain zero leakage.

Actuator parameters
Double acting Actuator: Two-position control of valve opening and closing.
Single-acting actuator (spring return): automatically closes the valve when there is a fault in the circuit or gas line control.
Double electric control solenoid valve: The valve opens when one coil is energized, and the valve closes when the other coil is energized. It has a memory function (explosion-proof type is available).
Single solenoid valve: The valve opens or closes when the power is supplied, and the valve closes or opens when the power is off (explosion-proof type available).
Limit switch transmitter: transmits the signal of the valve's open or closed position over a long distance (explosion-proof type available).
Electrical positioning switch: adjusts and controls the medium flow of the valve according to the size of the current signal (-) (explosion-proof type available).
Pneumatic positioning switch: adjusts and controls the medium flow of the valve according to the size of the air pressure signal (standard.-.).
Electrical converter: converts the current signal into a pneumatic signal and is used in conjunction with the pneumatic positioning switch (explosion-proof type is available).
Product application: widely used in petroleum, chemical and industrial environmental protection water treatment, high-rise buildings, water supply and drainage and other pipelines.
