OB-1,1G
Features
1. Easy plumbing due to union type connection screw.
2. No need for adjusting tool due to the attached adjusting
handle, making adjustment easy.
3. Double valve structure offers larger flow late than single
valve type.
4. Excellent accuracy since special packing is used for spindle
gland packing which affects opening/closing operation of
the valve.
5. The OB-1G ensures distinguished temperature resistance
due to external pressure type bellows.
