High-Pressure Socket-Connect Gradual On/Off Valves
- Valve Type: Gate
- For Use With: See Table
- Specifications Met: American Petroleum Institute Standard 602, ASTM A105N
With a forged steel body and bolted construction, these valves can withstand nearly 10 times the pressure of other socket-connect gradual valves. Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection. Also known as gate valves, they gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow.
The handle raises as these valves open and lowers as they close to let you know if flow is on or off. The stem also raises when on so it doesn’t contact what’s flowing through your line. This gives these valves a longer lifespan than valves with a nonrising stem. Also known as bolted bonnets, their flanged stem housing bolts in place for easy disassembly during maintenance. However, the housing makes them larger and heavier than valves with a threaded or welded housing.
Full-port valves don’t restrict flow.
Standard-port valves slightly 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.

- For Use With: Water
For a lightweight and economical alternative to metal valves, these are made of plastic. Insert unthreaded pipe into the socket ends and bond with PVC primer and cement to create a permanent, leak-tight connection. Valves gradually open and close to prevent system damage from suddenly starting and stopping flow. Pull the handle to open the valve. All valves have a rising stem that lifts as the valve opens and lowers as the valve closes to provide a visual indication of whether flow is on or off.
304 stainless steel gates are more durable than glass-filled polypropylene gates.

Gradual On/Off Valves with Solder-Connect Fittings
- Valve Type: Gate
- For Use With: Water, Oil
- Specifications Met: MSS-SP-80
Solder these valves to copper tubing for a permanent, leak-tight connection. They gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow.
Nonrising stems stay in the same position whether the valve is open or closed. Valves with nonrising stems are often used underground and in other low-clearance locations.
Rising stems lift as the valve opens and lower as the valve closes to provide a visual indication of whether flow is on or off. The stem is isolated from the process media for a longer service life than valves with a nonrising stem.
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.

Gradual On/Off Valves with Press-Connect Fittings
- Valve Type: Gate
- For Use With: Water
- Specifications Met: MSS-SP-80
For a leak-tight connection, crimp the press-connect fittings on these valves to metal tubing with a crimping tool (not included)—no heat or soldering required. The fittings are comparable to Viega fittings. These valves open and close gradually as the wheel handle turns, preventing sudden starts and stops of flow. They’re also known as gate valves. Made of bronze, they have good corrosion resistance.
Valves with a nonrising stem keep the handle in the same position whether they’re open or closed. They’re often used in low-clearance locations.
Valves with a rising stem lift up the handle as they open and lower it as they close. At a glance, you can see if flow is on or off. The stem is isolated from what’s flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem.
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.

Socket-Connect Gradual On/Off Valves for Chemicals
- Valve Type: Gate
- For Use With: Water, Carbon Dioxide, Citric Acid, Hydrochloric Acid, Isopropyl Alcohol, Kerosene, Natural Gas, Phosphoric Acid, Propane, Salt Water
- Seal Material: Fluoroelastomer Rubber
For a permanent, leak-tight seal, insert unthreaded pipe into the socket ends on these valves and bond with primer and cement. To withstand aggressive and corrosive solutions in chemical-processing applications, they have a fluoroelastomer seal and a plastic body. All gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow. Valves have a nonrising stem that stays in the same position whether the valve is open or closed.
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.

Plastic Socket-Connect Gradual On/Off Valves for Drinking Water
- Valve Type: Gate
- For Use With: Drinking Water
- Seal Material: See table
- Specifications Met: NSF/ANSI 61
Bond these valves to plastic pipe with PVC primer and cement (not included) to create a permanent, leak-tight connection in drinking water lines. Also known as gate valves, they open and close gradually to prevent damage to your system from sudden changes in flow. Turn the handle multiple times to start or stop flow. Safe for use in drinking water systems, these valves meet NSF/ANSI 61. They’re plastic, so they’re lighter in weight than metal valves.
All have a nonrising stem, which means that the handle won’t move up as the valve opens. This makes them good for underground and other low-clearance applications.
CPVC valves handle temperatures up to 200° F, so you can use them in hot drinking water applications.
Use repair kits to replace worn 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.

Gradual On/Off Valves with Press-Connect Fittings for Drinking Water
- Valve Type: Gate
- For Use With: Drinking Water
- Specifications Met: NSF/ANSI 61
For a leak-tight connection in drinking water lines without heat or soldering, crimp the fittings on these valves to metal tubing with a press-connect crimping tool (sold separately). The fittings are comparable to Viega fittings. Also known as gate valves, they open and close gradually to prevent damage to your system from sudden changes in flow. Safe for use in drinking water systems, these valves meet NSF/ANSI 61. They have good corrosion resistance since they’re made of bronze.
Valves with nonrising stems fit well underground and in other low-clearance places since the handle doesn’t move up when the valve opens.
Valves with rising stems let you see at a glance whether flow is on or off. The handle rises as the valve opens and lowers as it closes. The stem stays separate from the material flowing through your line, reducing corrosion so they last longer than valves with nonrising stems. With a long lifespan, you can use them for critical lines and lines that need to be opened and closed frequently.
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.
