• Extremely robust valves made from malleable iron, zinc plated & yellow chromated. • Brass throttle, malleable iron handle. • Self sealing, under pressure the conical throttle is pressed against the body, so the valve is sealed, no wear of seals. • With threads or claw couplings with rubber or brass seal. • When switching off pressure drop through exhaust from outlet side, therefore making it easy & a safe coupling release.
