Reliable Air Management for Municipal Water & Wastewater Systems
Tek-Sales supplies and supports the full line of DeZURIK APCO Air Valves, engineered to improve system efficiency, prevent pipeline damage, and eliminate air-related flow restrictions. From water mains to sewage force mains, these valves automatically vent air during filling and operation, and admit air during draining or vacuum conditions.
With both clean water and sewage-specific designs available, Tek-Sales helps engineers select the right air valve configuration for flow conditions, line size, and system type.
CLEAN WATER APPLICATIONS
APCO CLEAN WATER AIR RELEASE VALVES (ARV)
Designed to automatically vent air during filling and operation, these valves prevent air pocket formation in pressurized water systems.
-
Ideal for high points in potable water mains
-
Compact, corrosion-resistant design
-
Available in sizes 1/2"–3"
These valves admit air during draining and expel large volumes during system filling, helping prevent vacuum collapse and air lock.
-
Available as air/vacuum only or dual function combination valves
-
Protects pipes during filling, draining, or surge events
-
Sizes 1"–12"
APCO SINGLE BODY COMBINATION AIR VALVES (AVC)
Designed for clean water systems, the APCO AVC provides both air/vacuum and air release functionality in one body. Optimizing performance while minimizing installation space.
-
Combines large and small orifice venting in a compact design
-
Suitable for water mains and high points in pressurized systems
-
Sizes 1"–8"
CLEAN OR WASTEWATER APPLICATIONS
APCO HIGH PERFORMANCE COMBINATION AIR VALVE (ASU)
Engineered for clean or dirty water, these all-in-one valves combine air release, air/vacuum, and surge control in a compact body.
-
Combines 3 air functions into one valve
-
High capacity venting and surge protection
-
Available in water (ASU) and sewage (ASU-S) models
Used on storage tanks or pipelines, these valves admit air to prevent vacuum damage when draining or during negative pressure events.
-
Simple, fast-acting design
-
Ideal for tank venting and draining applications
-
Sizes 2"–8"
WASTEWATER APPLICATIONS
APCO SEWAGE AIR RELEASE VALVES (ASR)
Built for raw sewage and wastewater, these valves feature large orifices and self-cleaning float mechanisms to prevent clogging.
-
Corrosion-resistant and clog-resistant design
-
Operates at low pressure and in slurry conditions
-
Sizes 1/2"–3"
APCO SINGLE BODY SEWAGE COMBINATION AIR VALVES (ASC)
Combines air/vacuum and air release functions in a compact design optimized for wastewater and sludge applications.
-
Self-cleaning internal components
-
Prevents air lock and vacuum collapse in force mains
-
Sizes 1"–4"
Engineered for raw wastewater and sludge, the APCO ASV provides high-capacity air venting and vacuum protection with a dual-body design for added reliability.
-
Dual-chamber design separates air/vacuum and air release functions
-
Self-cleaning, corrosion-resistant internal components
-
Sizes 1"–8"
AIR VALVE OPTIONS
APCO SURGE CHECK VALVES (CSV)
The APCO CSV is an accessory designed to prevent water hammer and reduce surge by modulating air discharge during rapid filling or transient events.
-
Used with combination air valves to dampen pressure spikes
-
Adjustable to match system-specific surge dynamics
-
Compatible with multiple APCO valve models
APCO DOUBLE-ACTING THROTTLING DEVICE (DAT)
Installed on air valves to throttle both incoming and outgoing air, the APCO DAT allows fine-tuning of air flow rates to reduce slam and prevent system instability.
-
Used to control surge without sacrificing air venting capacity
-
Adjustable for site-specific flow rates and pipe conditions
-
Ideal for sensitive water and wastewater systems
