SKU CH-45RZ-JPNDG

Straight 1/8" steam air vent valve equalizes vapor pressure and vents at a rate equal to eight ordinary valves

  • Product typeDrain Components
  • Vent radiators far from the boiler efficiently
  • Equal venting capacity of eight ordinary air valves
  • Straight 1/8" connection fits standard radiator ports
  • Vapor equalizing design balances steam distribution
  • Install on upper-floor or cold-room radiators

Steam Air Vent Valve for Distant Radiators

The Gorton No. 6 1/8" straight vapor equalizing valve is designed for steam heating systems. It installs on radiators positioned far from the boiler or in colder rooms such as upper floors. The 1/8-inch connection fits standard radiator tappings for straightforward replacement or new installation.

Sustained Venting Capacity Under Steam Pressure

The valve provides continuous air venting capacity rated equal to eight ordinary air valves. This high capacity maintains rapid air expulsion during extended heating cycles, preventing air binding that slows heat delivery. The straight vapor equalizing design supports consistent operation throughout the heating season without performance drop-off.

Practical Limits of 1/8-Inch Steam Venting

The 1/8-inch pipe thread limits flow to the valve's rated capacity, which suits typical residential radiators but may restrict larger commercial units. It is not suited for water systems or high-pressure steam applications beyond standard low-pressure heating boilers. Buyers needing higher venting rates or different connection sizes require a different valve model.

Questions about this item

How much heat and noise does the No. 6 1/8" vent produce when the steam system runs all day?

The valve vents air silently through its 1/8" outlet; it has no moving parts that generate heat or mechanical noise during continuous operation.

What existing fittings must I already have to install this 1/8" straight vapor equalizing valve?

You need a radiator tapping or pipe with a 1/8" NPT female thread to accept the valve's male connection.

Will this No. 6 valve work properly on a one-pipe steam system that still uses original radiators and piping?

Yes, it is designed for one-pipe steam radiators; its venting capacity equals eight ordinary air valves, balancing older mains and distant radiators.
