Double Flange Concentric Butterfly Valve
Description Flanged Centric type Butterfly Valve is usually used water supply and drainage, gas pipeline for the temperature ≤80℃, nominal pressure ≤ 1.6Mpa to regulate the flow and cut off the fluid role. Range:DN50-DN1200 Connection type--Flange Working pressure:PN10/PN16 Temperature:-10-80℃ Fusion bonded epoxy coating

Lug Type Butterfly Valve
1. Long service life with reliable seal and without frequent maintenance. 2. Pressure Loss Too much pressure loss will bring increased cost of correlative energy. Butterfly valve have flow characteristics three times better than globe valve, and about 75% of a same size gate valve. 3. Multi-Function Butterfly valve can be used for on/off service and throttling. They are superior in Multi-function as compared to gate valves. Butterfly valve can be widely used in chemical field due to trim options and choice of elastomeric liner. 4. Weight Butterfly valve have feature of light in weight and small in size, for example, weight and size of a 10” butterfly valve are 1/9 and 1/6 of a 10” gate valve. So, butterfly valve is easy to be installed and saves cost of piping system. 5. Bubble Tight Butterfly valve with resilient seat design can be bubble tight as compared to metal seated gate or globe valves. 6. Easy of operation Butterfly valve offer 90-degree open to close.

Combination Nonslam Air Valve, 3 functions
Combination Air Release Valve Triple Functions / Anti-shock / nonslam ▪ discharge large air flow from water pipeline ▪ admit large air flow into water pipeline ▪ purge entrapped air from pipeline under pressure self-operating float type and can be fitted to any peak on a pipeline, capable of fulfilling the venting requirement of the pipeline and release any air or gas under pressure accumulated in the pipe system automatically.

Mud Release Valve
Mud release valve is a kind of angular truncation valve with hydraulic or pneumatic source as the actuator.Rows are usually mounted on the outside wall of the bottom of the sedimentation tank to remove sediment and dirt from the bottom of the tank. The valve is divided into two types: piston type and diaphragm type, each of which has its own characteristics. Product technical parameters Pressure level 0.6mpa-2.5 MPa pressure test GB/ t13927-2008 Suitable for medium water and weak corrosive liquid structure length GB/ t12221-2005 Applicable temperature 0 ° C to 100 ° C connection size GB/T17241.6-2008 Nominal diameter DN40~DN300 air cavity pressure (as a percentage of pipeline pressure) GB/ t12234-2005
