Product Description
1. The most economical corrosion / abrasion resisting valve available today -
versatile body and diaphragm materials.
2. Permanent bubble tightness against slurry , fiber and gases - resilient closure .
3. No contamination . The most suitable for the nuclear and food service - no gland
packing .
4. Simple in-line maintenance - easy to disassemble and reassemble . Can be made
without removing the body from the pipeline.

2) Weir Type Piston Operated Reverse Acting Valves ( Air-to-Open , Spring-to-close)
When it is desirable to close the valves in case of a failure in the supply of
operating pressure , this type of valve is recommended. Actuators are supplied in 2
kgf/cm2 and 4 kgf/cm2 operating Pressure.
3) Weir Type Piston Operated Direct Acting Valves ( Spring-to-Open , Air-to-close)
When it is desirable to open the valve in case of a failure in the supply of operating
pressure , this type of valve is recommended .
4) Weir Type Piston Operated Double Acting Valves ( Air-to-Open , Air-to-Close )
Being a springless Type valve , the double acting valve is much more compact than
the reverse acting valve. This type of valve may serve as either a normal open type or
a normal closed type valve depending on the control scheme .
5) Straight Way Type Handwheel Operated Valves
The hand wheel operated valve has the usual features of the weir type diaphragm
valve plus the features of the sluice valves . When fully opened , it froms a straight -
transfer passage as in a pipeline.

FAQ- Could you produce customized product?
Yes,we could do various customized valves conform to require drawing or sample. 2. How to ensure the valve quality??a.Firstly,we inspect the casting when get it one by one and will abandon it if defect castings.such as blowholes&pinholes is defects castings. b.We will inspect and check about valve dimension after machining.Allowable error to standard is 1.5mm for longth(above DN50 valves) c.All items must be inspected by hydraulic test after assemble.and more important ensure that valves are inspected by operator in according with hydraulic test criteria including pressure&time. d.Coat oil for anti-rust inside of the valve body and paint checking. 3. How is your valve warranty period?Usually,the warranty period for valves is 14 monthes,however,we will solve or replace new valves once find fault items to our old stock customers no matter how long.
