.jpg) | Air & Vacuum Valve Air & Vacuum valves are designed to vent large quantities of air when filling pipelines, and to allow air to re-enter pipelines when draining to prevent vacuum collapse. Valve Features: • Meets AWWA C-512 standards • Peripheral guide system for unobstructed closure • Drip tight closure Standard Materials: • Cast iron body with stainless steel trim • Standard Buna-N seating material • Optional materials and parts available Sizes: • 1/2" thru 24" available | ||
.jpg) | Air & Vacuum Sewer Valve Crispin Air & Vacuum Sewer Valves have a long body with a float near the bottom. The waste-containing solid remains low and away from working parts, venting the pipe line when filling, and permitting air to re-enter to relieve the vacuum. Valve Features: • Exhausts air as a pipeline fills, and allows air in as pipeline fills • Standard and short body series available Standard Materials: • Cast iron with stainless steel trim • Buna-N rubber seat • Optional backflush attachment Sizes: • Sizes 2" thru 10" available | ||
.jpg) | Vacuum Relief Valve The Crispin Vacuum Relief allows air to enter the system when a negative pressure occurs, but prevents air from being released under positive conditions, except through an optional small orifice Air Release Valve. Valve Features: • Cracks open to admit air at .25 PSIG differential pressure • Resilient drip tight seat • ANSI Class 125 & Class 250 flanged connection. Standard Materials: • Cast iron body • Bronze and stainless steel trim • Optional materials available. Sizes: • Sizes 3" thru 36". | ||
(t).jpg) | FOOT VALVE Installed on the pump suction, Crispin Foot Valves prevent the pump column from draining upon pump shutdown. Silent during operating and normally closed, the valve has a center-guided disc with a Buna-N seat to provide a drip tight seal. Valve Features: • Resilient seat provides positive shut off • Full flow area • Rugged construction for long life. Standard Materials: • Cast iron body • Bronze disc and seat ring • Stainless steel spring and inlet screen • Buna-N resilient seat. Sizes: • 2” thru 36” available. | ||
.jpg) | PL Series Pressure Air Release Valves Pressure Air Valves are used for the venting of accumulating air while the system is in service and pressurized. • Sizes: 1" thru 2" - Cast iron body; stainless steel trim. • Sizes: 2 1/2" thru 6" - Cast iron body; bronze trim; stainless steel float. | ||
.jpg) | M Midget Air Valve Midget Air Valves are used on hot and cold water systems, including irrigation systems where the venting of small accumulations or air is required while the system is in service and under pressure. • Sizes: 3/8" thru 1" - Cast iron body; stainless steel trim. | ||
.jpg) | AL / PL Series Dual Air Valve Dual Air Valves are offered with Pressure Air Valve piped out of the side of an Air and Vacuum Valve, providing a variety of combinations to meet specific air release requirements. • Sizes: 1/2" thru 24" - Air and Vacuum Valve piped to 3/8" thru 4" Pressure Air Release Valve. | ||
.jpg) | C Series Combination Air Release Valve Combination Air Valves consist of Air and Vacuum Valves and a Pressure Valve mounted in a single body, providing the integrity of a single body casting white permitting each valve of the combination to operate as a separate unit. • Sizes: 1/2 thru 24" - Cast iron body with stainless steel and bronze trim. | ||
.jpg) | UL Series Universal Air Release Valve These valves perform the function of both Air & Vacuum and Pressure Air Valves, permitting the application of various pressure orifice sizes for a range of air volume requirements under varying pressures. The design saves space and reduces cost. • Sizes: 2" thru 8" - Cast iron body; stainless steel trim. | ||
.jpg) | NP Series Negative Pressure Valve Negative Pressure Air Valves are applied where the interest is only in venting air to the atmosphere, and not permitting air to re-enter the system under vacuum. • Sizes: 1/2" thru 4" - Cast iron body; stainless steel trim. | ||
.jpg) | DL Series Deep Well Air Valve Deep Well Air Valves have an adjustable top which controls the velocity of air discharged from the valve. It also helps prevent chatter, and premature closure of the valve mounted on the discharge side of the pump. • Sizes: 1/2" thru 6" - Cast iron body; stainless steel trim. | ||
.jpg) | US Series Sewer Air Release Valve The Universal Sewer Air Release Valve performs the function of both the Air and Vacuum and Pressure Sewer Valves. This is accomplished all in one valve body. • Sizes: 2" thru 6" - Cast iron body; stainless steel trim. | ||
.jpg) | S / SL Series Combination Sewer Valve The Air & Vacuum Sewer Valve and the Pressure Sewer Valve can be piped together to perform a dual function at the high point. After the S Valve relieves the large volume of air in the line and seats, the SL continues to release entrapped air and gas accumulations while the system is in operation. | ||
.jpg) | X Series Valve Crispin Valve's exclusive X Series brings valve maintenance into the 21st century. All of the valve parts are stainless steel, making them impervious to rust. Instead of a bolted, flanged connection, the X Series features a stainless circular clamp to secure the valve head to the body. Available in Air & Vacuum, Pressure Air Release and Combination assemblies, the valve features our exclusive Head Exchange System, with its head fixed stainless steel internals. To clean, simply loosen the head assembly. Pull out the orginal head, and pop in a spare; then clean the orignal internals at your leisure. • Sizes: 2" thru 6" - Stainless Steel body; Buna-N gasket and seat. | ||
.jpg) | Tangential Flow Air Eliminator AE Series The Tangential Flow Air Eliminator separates large or small slugs of air from liquid systems while the system is in operation. • Sizes: 2" thru 24" - ASME code tank with cast iron body and stainless steel trim air release valve. | ||
