These joints have a rotating shaft with threads on one end that connect to a continuously revolving drum, roller, or other rotating equipment. Use them to transfer hot and cold materials from your supply line. Joints are for one-way flow and are meant to be used in pairs—one joint serves as the supply line while the other serves as the return line. Joints are stainless steel for excellent resistance to corrosion caused by fluid flowing through them.
If your drum rotates counterclockwise as you face the connecting end, you should select a rotating joint with right-handed threads. If your drum rotates clockwise as you face the connecting end, you should select a rotating joint with left-handed threads.

Threaded On/Off Valves
Use these valves in general purpose applications, such as those with water, oil, air, and inert gas.
Bronze valves are stronger and more durable than brass valves for a longer service life. Full-port valves do not restrict flow. Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

High-Pressure Threaded On/Off Valves
Rated for at least three times the pressure of standard threaded valves, these valves are used to start and stop the flow of compressed gas, pressurized water, or steam.
Lever handles are easy to open and close—they give you the most leverage of any handle type. Lockable lever handles can be fixed in place using a padlock (not included). Spring-close lever handles automatically close when you release them, so they’re good where the volume of flow needs to be closely monitored to avoid overflowing and spillage. They’re also called deadman’s handles.
316 stainless steel valves are more corrosion resistant than steel valves.
Standard-port valves slightly restrict flow.

Flanged On/Off Valves for Chemicals
Bolt these valves to ANSI flanges—they meet ASME dimensional standards. They have a plastic body and a seal that withstand aggressive and corrosive solutions in chemical-processing applications.
Glass-filled vinyl ester valves stand up to a wide variety of harsh acids and solvents. You can rely on them for repeated use, changes in pressure and flow rate, and hot and cold conditions.
Valves with a lockable lever handle can be fixed in place with a padlock (not included). They give you more leverage than short lever handles, so you can quickly open and close the valve with minimal effort.

Threaded Gradual On/Off Valves for Boiler Blow-Off
Prevent boiler scale deposits and sediment buildup with these valves that meet ASME standards for boiler drainage applications. Also known as gate valves, they gradually open and close to prevent system damage from suddenly starting or stopping flow.
Valves with a wheel handle open and close with multiple turns, providing more controlled, shock-resistant flow than valves with a lever handle.
Valves with a nonrising stem fit well in low-clearance places since the handle doesn’t move up when the valve opens.
Cast iron valves absorb vibration, reducing noise from your industrial boiler.
Use repair kits to replace worn-out seals.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Air-Driven On/Off Valves for Fuel


- Valve Type: Butterfly
- For Use With: Oil, Diesel Fuel, Ethylene Glycol, Kerosene, Butane, Fuel Oil, Gasoline, Natural Gas, Propane
- Seal Material : Viton® Fluoroelastomer Rubber
- Specifications Met: API 609, MSS-SP-67
Use these valves to safely transfer fuel and oil. They operate on compressed air to automatically start and stop flow faster than motor-driven valves. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve (not included). These valves don’t require a minimum pressure drop between the inlet and outlet for operation.
The actuator is directly mounted to the valve body to minimize movement and reduce wear. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. The manual override allows you to operate the valve during power outages.
All valves are lug style; their hole pattern matches ANSI flanges of the same pipe size. They can be sandwiched between two flanges, or bolt them directly to a single flange for servicing one end of the pipeline without depressurizing the other side.
Single-acting actuators only require air pressure to open the valve; they automatically spring closed when the air turns off. These valves are normally closed unless actuated. Double-acting actuators require air pressure to open and close the valve. Once actuated, these valves remain actuated until air pressure is applied, so they do not have a valve starting position.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

A 316 stainless steel body and a PTFE seal stand up to aggressive and corrosive solutions in chemical-processing applications. Their ball-valve design allows these valves to handle at least three times the flow of standard flanged valves. For faster actuation than motor-driven valves, they operate on compressed air. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve (not included). These valves automatically start and stop flow and don't require a minimum pressure drop between the inlet and outlet for operation.
Valves are full port, so they do not restrict flow. The actuator is secured to the valve body with a bracket for easy disassembly, maintenance, and repair. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. The manual override allows you to operate the valve during power outages.
Double-acting actuators require air pressure to open and close the valve. Once actuated, these valves remain actuated until air pressure is applied to close them, so they do not have a valve starting position.
