Valve System eliminates valve popping.

S-Transfer Parallel Valve System handles load variations beyond range of one valve by utilizing combination of control valves and regulators that transfer flow to valve best suited for current steam load. Suited for new installations or as retrofit, product resolves poor control situations and intermittent steam main pressure problems. Pneumatic switch selects which of 2 parallel circuits will be...

Steam Regulators eliminate need for 1/3-2/3 systems.

Able to handle fluctuating demands that require low turndown on some days and high flow on others, G Series Regulators provide 95% accuracy for minimal droop and have few moving parts. They are available air loaded in cast iron, bronze, carbon steel, and stainless steel in sizes Â-½-4 in. Integral pilot or temperature regulator versions are available in cast iron. All versions offer 100:1...
