  • These materials have proven heat and corrosion resistance properties.
  • A 360-degree anode is used to produce the highest possible grade of hard chrome finish.

These materials have proven heat and corrosion resistance properties. Each valve is designed using Finite Element Analysis software, and profiles are tested on our computerized flow bench. Strict attention is paid to the surface preparation of the valves, and the purity of the chrome is closely monitored. A 360 degree anode is used to produce the highest possible grade of hard chrome finish. White Diamond® Valves are light, strong, one piece forgings with profiles that provide excellent flow characteristics.

Shipping and Delivery

Some products we sell are shipped directly from distributor warehouses around the country.

Although certain items are kept in stock, some products are custom made to order and require manufacturing time.

Expected ship dates are our best estimate based on past shipping times and are more than 90% accurate. Should an unexpected delay in shipping occur, we will notify you by e-mail (or letter) of the new projected shipping date, and provide you with an opportunity to keep your order, or cancel it for a prompt and complete refund.

In-stock items usually ship the same business day (weekends and holidays are not considered business days).

Please allow an additional 1 to 5 business days after the shipment date for delivery.
