DRP Industrial Valves Price List 2026

Wafer-type cast iron butterfly valves to IS:13095-1991, ISI marked. S.G. iron or investment-cast CF-8 (SS-304) disc, fixed bonded liner in Nitrile (80°C max) or EPDM (130°C max), AISI-410 stainless spindle with AISI-304 pins and PTFE gland packing. Flange-compatible with BS:10 Tables D/E and ANSI B16.1. Gear operation standard at 200 mm and above.

PN-20 rated wafer butterfly valves to IS:13095, ISI marked, for higher shut-off duties — pump headers, high-rise risers, hydrant mains. Same construction as the PN-16 series: S.G. iron or CF-8 (SS-304) disc, Nitrile/EPDM bonded liner, AISI-410 spindle.

The heaviest butterfly class in the DRP range — PN-25 rated, IS:13095 ISI marked, S.G. iron disc on cast iron wafer body with Nitrile/EPDM bonded liner and AISI-410 spindle, for high-head pumping and pressure-zone isolation.

IS:13095 wafer bodies with CF-8 (SS-304) discs on PN-10 rating, fitted with rack-and-pinion pneumatic actuators (DBSP) or electric actuators (DBSE) for remote and automated isolation — ETPs, batching plants, OEM skids, pump houses. Solenoid and limit-switch accessories against indent; specify supply voltage and duty cycle at enquiry.

Compact non-slam check valves designed to API 594 and tested to API 598 — about one-eighth the weight of a conventional swing check. Ductile iron wafer body, single plate on stainless hinge pin, Nitrile/Neoprene/EPDM sealing; installs horizontally or vertically between standard flanges. ANSI 125/150 class.

Spring-loaded wafer-pattern check valves — two half-discs close before reverse flow establishes, the non-slam choice for pump discharge, fire risers and HVAC condenser lines. Cast iron bodies, D.I. or CF-8 (SS-304) doors on stainless springs and pins, Buna-N/EPDM seating.

Full-bore wedge-gate isolation valves to IS:14846, ISI marked, PN-16, flanged — cast iron IS:210 Gr.FG200 bodies with bolted bonnets. Non-rising stainless (DSV) or forged brass (DSB) spindles for chambers and buried service; rising spindle (DSVR) for visible open/closed indication; ductile iron resilient-seated DSVS with rubber-encapsulated wedge for drop-tight drinking-water duty.

Swing-type reflux valves to IS:5312, ISI marked, PN-16 — cast iron IS:210 body, bolted cover, rubber-faced door, flanged to IS:1538. Quiet re-seating with tolerance for suspended solids: the standard protection on centrifugal pump delivery lines, borewell headers and rising mains.

Compact cast iron globe-pattern isolation valves with brass spindles and teflon seats for drip-tight, low-cost shut-off on small bores — tanker filling points, float-valve isolation, utility take-offs. Screwed BSP, fully flanged or one-side-flanged ends.

Cast iron flanged air valves protecting rising mains, pump delivery lines and pipeline summits: single acting (DSAV) for continuous release of pressurised air at high points; double-orifice DDAV for large air volumes during filling and draining; kinetic DKAV for high-velocity discharge without premature closure on fast-filling mains.

Cast iron IS:210 Gr.FG200 strainer bodies with replaceable S.S.-304 / IS:410 perforated screens and CAF gaskets, flanged to BS:10 D/E/F with PN-16 drilling. Y-type Table-E (DSTF) for general duty; straight-through T-type (DTS) for in-line screen withdrawal.
