S&S Type B - Globe Style Sliding-Stem Valve
The S&S Series B is a single port globe-style body with composition or metal seats and a balanced "push-down-to-close” valve plug. There are three styles of valves available: Design "S&S BD” is intended for general control application over a wide variety of temperature and pressure drops. Design "S&S BT” is intended for applications requiring low leakage rates with composition seating (TFE) for tight shutoff requirements or metal-to-metal seating for higher temperature capabilities. The valve plug has a two-piece upper seal. Design "S&S BZ" valves are globe-style with integral end connections, post guiding, and quick-change trim. These valves are used in chemical or hydrocarbon processing applications or in applications that require control of non-lubricating, viscous, or other hard-to-handle fluids. *Flow Characteristics are Equal percentage, quick opening, The flow direction for standard cages ("S&S BD & S&S BT") is flow down, and the flow direction for the S&S BZ is up through the seat ring with the following flow characteristics available: linear, quick opening, and equal percent. The end connections are ANSI Class 150, 300 and 600 Raised Face or Ring Type joint flanges as per ASME B16.34-1996. Valve bodies are available in LCC, WCB and 316sst material.
S&S 857 - Pneumatic Diaphragm Sliding - Stem Actuator
The series S&S 857 is a direct acting, spring opposed diaphragm actuator with a 4-inch maximum travel. Signal pressure supplied to the upper housing chamber forces the stem downward. When the signal pressure is reduced, the compressive force on the spring moves the stem upward. If the signal pressure should fail, the spring will force the stem in the upward direction providing “ fail - open action” for “push-down to open” valves.
S&S SS25 - Vport Trunnion Ball Valve
The SS25 Series V Port Ball Valves are American made and are an economical choice for your control valve needs. The benefits of the V Port ball valve over other control valves is that is shuts-off as well as it controls. SS25 Series V Port ball valves were designed specifically for the Pulp and Paper, Petrochemical, Oil and Gas Industries.
S&S Type H Control Valve
The HPX Control Valve is a rugged single port high-pressure globe valve, with metal seats, quick-change trim and push down to close plug action. The HPX2 uses a balanced valve plug, and piston rings are used to provide the seal between the valve plug and cage. The HPX5 uses a balanced valve plug, and a pressure-assisted spring seal to provide the seal between the valve plug and cage. For standard cages, the flow direction is flow down with the following flow characteristics: equal percentage, modified equal percent, and linear. The end connections are Class 900 and 1500 raised face and ring type joint flanges as per ANSI B16.34 196. Valve bodies are available in LCC, WCB and 316sst material.
S&S 3400 Digital Posioner Explosion Proof
SS3400 series Smart Valve Positioner accurately controls valve stroke in response to an input signal of 4-20mA from the controller. Built-in micro-processor optimizes the positioner’s performance and provides unique functions such as Auto-Calibration, PID Control, Alarms, and HART Protocol Communications.
S&S 4150 - Pneumatic Controller
The S&S 4150 and 4160 are pneumatic pressure controllers that utilize a bourdon tube or bellows for sensing vapor, liquid or gas pressure, and differential pressure. The S&S controller can be reconfigured from direct, to reverse acting or vice versa without any additional parts.
