STONE Ball Valves
STONE ball valves are very suitable for steam, the seat and packing have excellent resistance to high temperatures and the raw materials are imported from Japan, which allows STONE ball valves to last long on textile machinery and only require replacement parts, creating higher efficiency and lower costs for the end-users.

STONE Butterfly Valves
The butterfly valves in textile mills need to be opened and closed frequently, which requires the seat material not only to have the ability of durable elastic sealing, but also to maintain the toughness under the long-term working condition. STONE butterfly valves not only have a tight shutoff performance, but also have a low cost of seat replacement.

Standard Specification

ST Series Double Acting Pneumatic Actuator Selection

Before Using a double-acting actuator, we need to determine the torque of the valve, if works for steam/vapor or non-lubricated medium, please add a 25% safety factor. If works for non-lubricated dry air medium, please add a 60% safety factor. If works for non-bribery with gas transport granular medium add 100% safety factor. And for a clean, frictionless lubricated medium just add a 20% safety factor, then according to the air source pressure, find the double-acting torque table, and you can get the right ST model. For example the air supply is only 5 bar, ball valve torque requests 180N.m, the medium is non-lubricated steam, taking into account the safety factor, add 25% equals 225N.m, first look up the air supply 5 bar according to the table, then look up the torque data equal or similar along the vertical, select 247 to 319N.m, then look up the model number along the line to the left, select model ST-125 pneumatic actuator is perfect.
