Low-profile drain valve

SITECH EXHAUST VALVE:

• Low profile
• High-flow exhaust valve
• Semi-automatic
• Ratchet Action: when you turn the valve from the open to closed position (or vice-versa), you hear a "Click"; this is called Ratchet Action or Stop Action. This sound helps to adjust the valve, as by counting the number of "Clicks" you can ensure that the valve is in the same position as previous times (adjusted to your needs)
• Wide profile (referring to seat engagement)
• Anti-friction seal
