Double angle valve

Product Description

The double angle valve is a versatile flow control device. It regulates fluid movement in plumbing, heating, and industrial applications.

This valve features a 90-degree angled body with two inlet or outlet ports. This allows efficient redirection and control of water, steam, or other media within compact piping networks.

Available in configurations ranging from dual-outlet supply stops for residential plumbing to specialized radiator valves for hydronic heating systems, the double angle valve provides reliable shut-off capability. It simplifies complex piping layouts.

What Is a Double Angle Valve and How Does It Work?

A common question is how this product differs from standard valves.

A double angle valve is a specialized shut-off valve with a body that creates a 90-degree turn in the flow path. This distinguishes it from straight or globe valves.

The “double” designation typically refers to either dual outlets from a single inlet or the ability to control flow in two separate circuits from one valve body.

When the handle is turned, an internal ball or compression mechanism opens or closes the flow path. This allows precise control of fluid movement to connected fixtures or appliances.

In heating applications, double angle valves serve as radiator connections that accommodate tight spaces while providing thermostatic control options.

What Types of Double Angle Valves Are Available?

Double angle valves are manufactured in several configurations and materials to suit different applications.

Dual-Outlet Angle Supply Stop:
This features one inlet and two smaller outlets. It allows a single water supply line to serve two fixtures such as a kitchen faucet and dishwasher.

Double Angle Radiator Valve:
This is designed for hydronic heating systems. It connects radiators to piping networks in tight spaces. It is available in left and right versions with thermostatic actuator compatibility.

Double Angle Distributor for One-Pipe Systems:
This specialized valve is for one-pipe heating systems. It distributes flow to radiators while maintaining system balance.

What Materials and Finishes Are Available?

The double angle valve is constructed from various materials to balance durability, corrosion resistance, and aesthetic appeal.

Solid Brass:
This offers high corrosion resistance and excellent durability. It is suitable for high-pressure systems. It is best for water supply lines, HVAC systems, and commercial plumbing.

Chrome-Plated Brass:
This has an attractive mirror-like finish. It resists fingerprints and is easy to clean. It matches modern fixtures. It is best for bathrooms, kitchens, and visible residential installations.

Nickel-Plated Brass:
This offers a durable finish with good corrosion resistance. It has a professional appearance. It is best for heating systems, exposed plumbing, and commercial applications.

Brass Chrome Premium:
This combines brass strength with chrome elegance. It offers superior corrosion resistance and smooth operation. It is best for high-end residential plumbing, heating systems, and luxury installations.

What Are the Key Specifications of Double Angle Valves?

Typical specifications for double angle valves include specific measurements and ratings.

The inlet size is typically 1/2-inch compression or threaded connection. Outlet sizes are typically 3/8-inch or 1/4-inch OD compression.

The valve type is typically a 1/4-turn ball valve or compression stop. Maximum operating pressure is 125 to 200 PSI.

Maximum operating temperature is up to 180°F for potable water. It is up to 240°F for heating applications. The body configuration is a 90-degree angle pattern.

The handle type is single or double handle, allowing individual control per outlet.

What Applications Are Double Angle Valves Used For?

The double angle valve serves critical functions across multiple industries and applications.

In residential plumbing, it controls water flow to kitchen faucets, dishwashers, ice makers, and water filters from a single supply line.

In dual vanity installations, it allows two sink faucets to be supplied from one water source. This simplifies under-sink plumbing.

In hydronic heating systems, it regulates hot water flow to radiators. The angled design accommodates tight spaces between walls and radiators.

In commercial plumbing, it provides reliable shut-off for multiple fixtures in office buildings, hotels, and restaurants.

In industrial process systems, it controls aggressive fluids in chemical processing and manufacturing facilities.

In steam and condensate systems, it manages steam flow in power plants, industrial boilers, and sterilization equipment.

How Do You Install a Double Angle Valve?

Proper installation requires attention to compatibility and sealing.

First, verify compatibility. Confirm the valve material is suitable for your fluid type.

Second, prepare the pipe. Cut and deburr copper, PEX, or CPVC pipe to the appropriate length. For push-to-connect models, simply insert the pipe fully into the fitting. No tools are required.

Third, apply sealant. For threaded connections, apply PTFE tape or pipe joint compound to male threads before assembly.

Fourth, tighten securely. Use appropriate wrenches to tighten connections. Avoid over-tightening, which can damage threads or crack the valve body.

Finally, test for leaks. After installation, turn on the water supply slowly. Inspect all connections for leaks. Most quality double angle valves are 100% leak-tested at the factory.

What Safety and Compliance Certifications Should You Look For?

When selecting a double angle valve for potable water applications, look for products that meet relevant safety standards.

NSF/ANSI 61 certification ensures materials do not leach harmful contaminants. NSF/ANSI 372 certification ensures lead content compliance with a maximum of 0.25%.

ASME A112.18.1 is the standard for plumbing supply fittings. CSA B125.1 is the Canadian standard for plumbing fittings.

How Do You Maintain a Double Angle Valve?

Periodic maintenance extends the life of your double angle valve.

Exercise the valve by operating the handle through its full range every 6 to 12 months. This prevents seizing.

Inspect for leaks around the stem and connections annually. Check for any signs of moisture.

Clean chrome finishes using mild soap and water. Avoid abrasive cleaners that can scratch plated surfaces.

Protect from freezing. In unheated areas, drain or insulate valves to prevent freeze damage.
