Safety valves

Lift lever and soft seat configurations

The Series 211 and Series 632 safety valves for air, gas, steam, and liquid applications are designed to provide reliable overpressure protection in system components. They feature a dual-ring construction to offer reportedly easy adjustment, precise opening, and high volume, short blowdown with high liquid flow capacity. The disk and nozzle are changeable to accommodate changing conditions and processes. They are ideal for a variety of applications, including air and gas compressors, piping, boilers, and accumulators.

Amplifying nozzles

Reduces air consumption

The Energy Saver air nozzles and jets are designed to significantly reduce compressed air consumption by amplifying the air output. Its design forces the air through a 0.002-inch annular orifice, accelerating airflow and entraining surrounding air as it exits the nozzle. Airflow volumes out of the nozzles are reportedly 25 times more than the compressed air supplied. A range of high and low thrust models are offered.

Standard length of 25 ft

With a reinforced construction that is designed for long life, the AHPLUS flexhose can withstand a temperature range from -60 to 275F. It is featured in a royal blue color so it may be easily visible in both small and industrial settings. It is reportedly moisture- and tear-resistant and has a higher temperature range than neoprene/fabric hoses. It is ideal for such applications as dust collection, bridge painting, industrial ventilation, drying, boat building, and fume collection.

With ideal sealing material

The 32-port custom valve solution is based upon a standard inert rotary valve that features a stainless steel rotor and a PTFE body that reportedly is virtually inert to all chemicals and stable up to 200C. It features internal 4-mm diameter flow paths and an optical encoder that is designed to accurately position the rotor and maximize flow rates. It is driven by a 24V dc motor using computer-controlled TTL compatible signals, and it measures 210 x 140 x 110 mm.

Diaphragm check valve

Not dependent on gravity

Designed for use with highly aggressive or ultra-pure liquid applications, the Series CKM diaphragm check valves reportedly maintain bubble-tight seals in whatever position they are mounted. Its patented diaphragm is intended to automatically position itself against the valve seat in an identical location each time. They are chatter- and leak-proof and have no internal sliding or loose parts to slam or vibrate, according to the company. They are available in sizes .50, .75, and 1 inch NPT.
