WEATHERMATIC 12000 SERIES IRRIGATION VALVES:

Weathermatic 12000 Series Valves feature superior materials, four-bolt covers, an unmatched manual bleed, a shock cone to reduce water hammer and a revolutionary reverse flow design which prevents valve failure in the open position. Excellent for micro-irrigation as valve will operate as low a 1 GPH. The unique "reverse flow" porting design permits equal pressure distribution on both sides of the diaphragm, regardless of line pressure providing zero stress to prevent "stretching," a common cause of valve failure.

• Unique "reverse flow" porting design permits equal pressure distribution on both sides of the diaphragm, regardless of line pressure providing zero stress to prevent "stretching," a common cause of valve failure
  
• Reverse flow design for water conservation in the event of failure
• Diaphragm's self cleaning ports constantly flex, inhibiting sand and silt from blocking valve action
• Molded shock cone for smooth operation and reduction of water hammer
• Easy-to-use internal manual bleed lever; bleeds valve downstream; has stops for open and closed positions
• Marine-grade S20P solenoid with stainless steel actuator
• High-strength glass-filled nylon body and cover with 1/4" stainless steel cover bolts and mating brass body inserts
• Non-rising flow control stem throttles valve from full open to closed position on flow control models
