Ball Valves
We manufacture floating and trunnion design ball valves,
side entry and top entry. Our valves are designed for a wide range of
applications like oil and gas, both upstream and downs tream, chemical
and petrochemical industry, as well as for power production industry nuclear
power plants, thermal power plants and hydrochemical power plants.
Ball valves are designed to API 6D, ANSI B16.34, and
API 6D. Other standards can also be met another standards involved in
the manufacturing of the ball valves are: ANSI B16.5, ANSI B16.25 or ANSI
B16.10. Ringo ball valve are fire safe designed to meet BS6755 API 607.
The applicable testing standards are MSS-SP-61, API
6D or API 6A.

Materials
We can design our valves selecting a wide range of material.
- Carbon steels
- Alloy steels
- High resistant steel for API 6A valves
- Stainless steel
- Duplex & Superduplex
- Nickel alloys
Materials can meet NACE MR-075/ISO 1556 requirements
if so required our technical department will choose the most appropiate
material according to service conditions and customer requirements.
Special Valves
Valve with counterweigh |
- Valve with counterweight
This type of valve is designed to protect the turbines and pumps
in the hydroelectrical plants. Valve is fitted with hydraulic actuator
to open the valve.
When there is counter flow that may damage the pump/turbine, the
pressure is delected by a pressure switch that sends a signal to the
hydraulic actuator and the valve is closed in few seconds.
- Three or four way ball valves
- Ball valves interchargeable in live.
Being same configuration that of standard top entry design valves, this
valve for sizes up to 6” is for more economic than the top entry.
