STOCKHAM® Cast Steel Valves

Brands: STOCKHAM® Product Family: Process Valves Product Type: Cast Steel Valves, Gate, Globe, Check & Angle Valves 
Type: Drawing

Stockham® globe valves are highly efficient for services requiring frequent operation and throttling when pressure drop across the valve is about 20% of inlet pressure. Closer throttling, creating higher pressure drops may cause cavitation or excessive velocities which could cause high noise levels, vibration and possible damage to the valve or adjacent piping. Globe valves can be equipped with optional operators and are available with a variety of trims to match service requirements.

STOCKHAM® Iron Valves

Brands: STOCKHAM® Product Family: Process Valves Product Type: Gate, Globe, Check & Angle Valves, Iron Valves 
Type: Drawing

Stockham® iron body valves are proven performers in mechanical systems of commercial buildings throughout America. Chemical plants, steel mills, shipyards, refineries, pulp and paper mills, and utilities have also found that Stockham® iron body valves do the job better and longer for their many general services.

UNI-CHEK® Check Valves

Brands: UNI-CHEK® Product Family: Process Valves Product Type: Check Valves 
Type: Drawing

Uni-Chek® Check Valves provide check valve performance with large opening angle resulting in high Cv performance. Much lighter and easier to handle and maintain than conventional swing check valves they provide an economic solution and protection for systems with a low reverse velocity.

WTA® Change Over Valves Types 11.7, 11.8, 11.75 & 11.85

Brands: WTA® Product Family: Process Valves Product Type: Change-Over Valves 
Type: Drawing

WTA® Change Over Valves are used to connect two safety valves to a pressure system using one pipe point. Here, one safety valve is in operation and one safety valve is on stand-by. The stand-by valve can be removed during ongoing operation for service, while protection of the pressure system against inadmissible pressures is maintained. The use of change over valves allows essential maintenance work to be carried out on a safety valve, without interruption of the plant operation. This is realized by simply switching over to the relevant stand by safety valve, thus protecting the plant against excessive overpressure.
