Premium Wrot Copper Welded Ball Valve (Sweat x Sweat Connection)

Engineered for heavy-duty plumbing, HVAC, and refrigeration systems, our Premium Welded Ball Valves provide a highly dependable inline shut-off solution with a permanent, leak-proof mechanical joint. Featuring precision-machined female sweat (cup) ends, these valves are designed to be brazed or soldered directly onto copper tubing, eliminating the risk of thread or gasket failures over decades of high-vibration and high-pressure service. 

Equipped with a smooth, heavy-duty quarter-turn handle, this full-port ball valve ensures maximum fluid delivery with zero pressure drop. The robust forged brass body and wrot copper extensions easily withstand the intense heat required for proper field torch-brazing without warping or damaging the internal seals. 

Key Features and Benefits

Permanent Sweat Connections: Designed with precision-machined cup sockets that allow brazing alloys or solder to pull in evenly via capillary action. This creates a fused, permanent structural bond built to eliminate bypass leaks.
Full Port Fluid Flow: Designed with a full-port internal opening that matches the inside diameter of the connected copper pipe. This ensures maximum water or refrigerant velocity with zero flow restriction, protecting your system pressure.
High-Heat Resistant Seals: Built with premium Teflon (PTFE) seats and durable EPDM O-rings engineered to withstand standard installation torch-brazing heat, as well as extreme continuous working temperatures.
Quarter-Turn Shut-Off Control: Features a smooth, heavy-duty steel lever handle that provides instantaneous water or refrigerant isolation with a simple 90-degree turn, making system maintenance or emergency shut-offs effortless.
Lead-Free Heavy Brass Construction: Forged from high-grade, lead-free brass, meeting strict NSF/ANSI 61 and NSF/ANSI 372 standards, making it completely safe for domestic drinking water as well as mechanical HVAC lines.
Blow-Out Proof Stem Layout: Features an industrially designed, blow-out proof pressure stem that guarantees user safety and valve integrity even under sudden system pressure spikes or extreme thermal loads.
