SV-1600A Valves

SV-1600A Valves

SV-1600A

Questtec Solutions Type SV-1600A valves are designed specifically for use with water level gauges in steam/water service. The angled flow path compactly facilitates installation of the level gauge bringing the assembly connection point to the side. The valve has a reciprocating stem that does not rotate, maximizing packing life and preventing galling of the valve seat. The lower valve is normally supplied with a blowdown/drain connection. As with all Steam-Trac products, integrity of design and maximum service life are the foremost considerations.The valve body and yoke are fabricated from forged carbon steel. The stem and seat are 416 SS (13 CR), and are both replaceable. Optional closing action is available: 2-1/2 turn (plain closing), or 1/4 turn (quick closing.) The valve can be supplied with handwheels, levers (1/4 turn, only) or chain wheels. For connection to the gauge, Questtec recommends either 1/2” Uniflex unions or flanges. The Uniflex gasketed union offers a high integrity seal, and virtually eliminates nuisance leakage typically associated with stuffing box connections. Although available, Questtec Solutions does not recommend using a stuffing box connection, as is commonly supplied by our competitors. Although they allow flexible orientation and are very forgiving dimensionally, they are normally fabricated from 0.75” OD Tube, which is actually smaller than the minimum 1/2 IPS* as required by ASME Section 1, PG 60. Drum or Water Column Connections are normally 3/4” flanged, 3/4” male IPS, although additional options are available. * 1/2 IPS is has an actual OD of 0.84”. This rarely realized discrepancy has resulted in many surprise inspection findings

SV-450 Valves

SV-450 Valves

SV-450

The SV-450 valve is specifically designed for use with a boiler water level gauge glass. This valve is supplied as a valve set including one top valve, and one bottom valve. Each valve has 3 connection ports available in a wide range of sizes and types, (vessel x gauge x vent/drain). The angled flow path facilitates compact installation of the gauge glass, bringing the assembly connection point to the side. The offset body pattern allows a direct path around the stem to clean through the vent/drain ports. The standard vent/drain ports are 1/2″ F.NPT, 3/4″ F.NPT and SW are also available. The vessel connection features a floating union tail piece to allow vertical fit up mounting. If eliminating the vessel union is desired, a non-union solid shank connection is available in 3/4″ IPS pipe stub, or flanged. Ball checks are omitted in standard form, and available as an option. Ball checks are neither required nor prohibited by ASME Section I.
